Features of papillomatous nevi

If a bumpy mole resembling papilloma appears on the skin in the hairy part, it is a papillomatous nevus. The tumor has a benign nature, for medical reasons to be removed. When hilly moles appear, it is required to contact a dermatologist to correctly differentiate the disease. A papillomatous nevus of the skin rather causes a cosmetic defect, since by its specificity it is considered melanoma. Leaving such a mole without attention is highly undesirable.

What is papillomatosis nevus

Externally, this is a birthmark of a brown color, which has an uneven bumpy surface, often localized in the scalp. However, this factor is more dependent on the type of papillomatous nevus, its origin. In any case, we are talking about a cosmetic defect, and not about malignant tumors, although patients with such benign tumors are still at risk. It is important to consult a dermatologist in time, clinically to exclude melanoma.


Nevus papillomatous may vary in color and location on the body, has different parameters in diameter with a cyclically round spot shape. Typical localization - the scalp, neck, face, less often - other areas of the skin of the body. In modern medicine, we are talking about congenital and acquired nevi, which, with pathological changes in structure, can mutate into a malignant neoplasm. When pigmented neoplasms appear, it is very difficult not to notice the visible pigmentation of the dermis.

A characteristic feature of the pigment nevi is the presence of short hairs in the area of ​​bumpy moles - by this feature it is distinguished from other growths on the skin. In addition, such benign tumors are found from light purple to black. Nevus papillomatous different clear outlines, a variety of shades of brown. Other symptoms of the characteristic disease are presented below:

  • gradually increasing the nevus in size,
  • constant discomfort,
  • increased trauma to the dermis,
  • friability and heterogeneity of structure,
  • single or multiple education,
  • bulge above the surface of the dermis,
  • psychological discomfort.

Reasons for education

A papillomatous nevus of the scalp is formed in the prenatal period, but after the birth of a child, it does not appear immediately. It is possible that the pigment accumulates in the cells for many years, and the characteristic stain appears only by the age of 30 or at an older age. Doctors cannot determine the main causes of dark spots of a dense structure; therefore, the pathological process is attributed to gene mutations, prenatal pathologies.

Types of papillomatous nevi

Detailed diagnostics is accompanied by mandatory histological examination in order to correctly differentiate the diagnosis against the background of the existing classification. Doctors distinguish the following types of nevi papillomatous according to different evaluation criteria from patients of all ages.

In appearance:

  • pigment - formed on smooth skin without hair,
  • hair - develops in the scalp,
  • verrucous - localization is difficult to predict, outwardly, the nevus resembles a cauliflower in structure.

The shape of nevi are:

  • organic - with such birthmarks, there is a wide base and elevation on the surface of the dermis,
  • disseminated - accompanied by extensive lesions of the central nervous system, chronic epilepsy.

According to the specifics of the development of the pathological process:

  • intradermal,
  • papillomatous,
  • melanocytic nevus.


It is necessary to fear the rebirth of a mole into a malignant neoplasm, therefore there is an urgent need for the timely excision of a nevus by operational methods. In addition, the characteristic growth in life is systematically exposed to damage, which is accompanied by dangerous inflammation and infection of the dermis. Especially dangerous is the appearance of fibroepithelial nevi. Among the potential complications, doctors also distinguish the following pathological processes:

  • severe pain and redness of the dermis,
  • the risk of scarring after scratching a nevus,
  • skin infections, skin infections.


The main purpose of a detailed diagnosis is to exclude the presence of cancer cells and contraindications for the operation. To do this, in addition to visual inspection of papillomatous tumors, a biopsy is necessary as an informative method for assessing the nature of the growth on the upper layer of the epidermis. From additional surveys are needed:

  • dermatoscopy to distinguish papillomatosis nevus from other types of growths, for example, filiform warts, border nevi, melanoma,
  • Siaskopichesky research in the form of scanning pigment neoplasms of the skin to determine the chemical composition.

It is not always effective to use conservative methods of intensive therapy, however, some folk remedies accelerate the therapeutic effect after surgical intervention. Photo of characteristic growths scares their appearance, so do not wait for the growth of moles and act immediately. The attending physicians give the following recommendations for dysplastic nevus and not only:

  1. If the birthmark is located on the head, the risk of its systematic injury to the comb increases. Therefore, such growths are best removed in a timely manner. If a nevus on the body does not cause internal and external discomfort, it can only be observed.
  2. This kind of growths is required to be observed by an oncologist, and for this, 1 time in 6 months to make an appointment with such a specialist, to undergo a detailed examination of the epidermis.
  3. When a large mole is detected on the body or in the hair, a histological examination is necessary to identify the nature of the characteristic neoplasm.

Surgical removal

Many patients are attracted to a photo without a papillomatous nevus, so every second person seeks to immediately remove it. Surgical intervention is carried out only after a detailed diagnosis in order to eliminate the risk of developing oncology and the dangerous consequences of the operation. The advantage of this radical method of treatment is the long-awaited exit from the risk group, and the disadvantages are the sometimes painful procedure, scars and scars on the body. There are several methods for removing growths, the most suitable doctor determines on an individual basis.


In this case, the focus of the pathology with the help of special equipment is affected by liquid nitrogen with the participation of low temperatures. The cold productively excludes the affected tissues, contributes to the death of the nevus. Such a surgical procedure is suitable if the center of the pathology is located in the hair or is covered with clothes, since even after the final recovery, there may be ugly scars and scars on the body. So it is better not to carry out a cryodestruction on the face. Among the significant advantages - the final disposal of nevus papillomatous.

Laser removal

This is one of the most progressive and safe minimally invasive warts removal techniques. The procedure is performed under the influence of a powerful heat flux, which destroys the tissue of the pathogenic growth to the very foundation, makes the skin smooth and even. Doctors distinguish the painlessness of the session, reduced risk of bleeding, the final solution to the aesthetic problem, and the short-term rehabilitation period among the advantages of laser exposure. Disadvantages are the complexity of diagnosing oncology and the high cost of the procedure.

Radio wave removal

The procedure is almost painless, the rehabilitation period is characterized by its short duration. Radio wave surgery retains biological material for histological examination, is a non-contact method of removing growths on the skin. Scars and scars are almost invisible, the problem of aesthetic nature is completely solved. Among the benefits, doctors emphasize reduced risk of infection and external changes. Disadvantages - the presence of contraindications and side effects.


This is a bloodless, minimally invasive method of removing a nevus, in which low-frequency electrical currents affect the pathology. The procedure is safe and relatively effective, allows you to further conduct a histological study, but among its shortcomings is the emergence and preservation of the scar in the place of the direct burning of the wart. In addition, excision of tissues sometimes does not occur in full, a repeated procedure is required.

Folk methods

For productive elimination of the papillomatous virus, patients do not always decide on the operation. Some of them trust more methods of alternative medicine, which are also recommended to be implemented under strict medical supervision. Here are effective folk recipes that lighten the nevus or contribute to its early death:

  1. Juice celandine. It is recommended to cauterize a mole with such a concentrate in the morning, noon and evening in the complete disappearance of the brown spot. Previously it is important to ensure the integrity of the skin, to eliminate oncology.
  2. Lemon juice. Such a concentrate in case of nevus papillomatosis of different origin acts on the same principle. Use lemon is allowed only in the absence of an allergic reaction on the skin.


To exclude the appearance of papillomatous nevus, it is necessary to adhere to preventive measures. This is especially true for at-risk patients and people with a genetic predisposition for this type of growth. Effective prevention measures are presented below:

  • complete refusal to work and contact with chemical reagents, toxic substances, poisons,
  • reduced contact with household chemicals (rubber gloves are recommended),
  • early departure from environmentally unfriendly habitat (climate change, living conditions),
  • reducing the risk of radiation exposure,
  • rejection of all bad habits.

Classification of papillomatous nevi

This type of papillomatous nevi is classified by appearance and form. Let us consider in more detail the features of each variety.

Papillomatous nevi in appearance are divided into:

  • pigment - nevi dark almost black shades, may be in any area of ​​the body except the head,
  • hair - nevi, on which or from which grow quite long hair (sometimes),
  • verrucous - it can be confused with a warty nevus, but the verrucous has a more bumpy surface and deep folds. Most often, it is dark in color and this type of nevus on the body is usually one.

Intradermal papillomatous nevi also distinguished by the form:

  • The most common form is considered organic. Nevi of this form are formed in the singular and usually have a brown color. In addition, the nevus "sits" on a broad basis, rather than on a thin stalk, and has a very dense structure, since it consists of dead cells.
  • Nevi disseminated forms are formed on the body in the set, and they look like small plaques. Over the course of a person's life, they may disappear or resize.

An excessive number of papillomatous nevi on the human body may indicate a possible development of epilepsy or CNS disorders.

Causes of papillomatous birthmarks

The reasons leading to the formation of intradermal moles include the following:

  • injuries
  • heredity
  • hormonal background
  • Sun rays
  • viral infections
  • skin development defects

Let us consider in more detail each of these factors.

Skin injuries as the cause of the appearance of such moles are considered a rare and secondary factor. Some experts in this field say that small wounds, scratches or insect bites can affect the formation of a nevus. The inflammatory process that accompanies these mechanical damages can provoke cell growth, since at this time biologically active substances are locally released to heal the damage.

Very often nevi transmitted by genes. The birthmark of the parent is encoded in the DNA molecule by genes. When a child is conceived, this information is inherited. In 50% of cases, this nevus will manifest itself, if the parent has inherited it. If a parent has a nevus in life, that is, it has been acquired, then it will not be transferred to the child, since there is no information in the genetic material about it.

During the study of nevi, it was observed that hormones are involved in their formation. Scientists note that during puberty or during pregnancy, or in cases of endocrine disorders may appear nevi. That is, these are the cases when hormones are very active in the body, hormonal changes are rearranged or it is disturbed. When observing such moles, it was noted that they very rarely turn into malignant tumors and may disappear without any treatment within a few months after their appearance.

Sun rays (and tanning beds) are another risk factor especially for women over 30 years old. Under the influence of sunlight, the body intensively produces a large amount of melanotropic hormone, and the skin color changes. However, if ultraviolet light continues to penetrate the skin, an increase in melanocytes may occur in the body. That is, skin cells can begin rapid growth and as a result it will cause the formation of a nevus.

Modern medicine at the moment considers as a reason for the formation of intradermal moles also bacterial and viral diseases skin integument. The reason for this was several similar incidents that occurred in different regions of the globe. The scheme of the appearance of a nevus in this case is the same as with injuries, that is, the basis is the active process of inflammation of the skin cells.

And, finally, a secondary cause of the formation of moles - skin development defects. ATDuring the late period of prenatal development of the fetus, division disorders can occur in the skin cells. After birth, these defects are invisible, but can appear as moles in 2 or 3 years.

Risk groups

For these reasons, groups of people are identified who are particularly at risk for developing skin cancer from an intradermal nevus.

  • people under the open sun constantly or often
  • people who constantly leave for vacation in equatorial countries,
  • people working in the chemical industry with carcinogens,
  • people who have undergone long-term hormone therapy
  • people with weak immunity and suffering from endocrine disorders,
  • people who have a large number of congenital moles,
  • people who have relatives with skin cancer.

All of these groups of people should more often go to doctors for a checkup and avoid situations that can provoke the degeneration of a nevus into a malignant tumor.

Since papillomatous nevi are often have innate character Due to abnormalities in the cells of the fetus, pregnant women should protect themselves from:

  • strong and direct sunlight
  • toxin poisoning,
  • urinary tract infections.

And also to control the balance of estrogen in the blood.

If the papillomatous birthmark is located on the head, it can cause its damage during combing, and this is a reason to consult a doctor. Such a nevus is better to remove.

Treatment of papillomatous education

If you find damage to the nevus, blood on it, redness around the mole, you feel discomfort or noticed that the mole is growing, then this may be the reason for its removal. In addition, nevi of this species have an unaesthetic appearance and this is also the reason for their removal.

Among the possible methods of treatment papillomatous nevi distinguish the following:

  • laser treatment or surgery
  • radio wave method
  • cryodestruction
  • electrocoagulation

The choice of method of treatment the doctor chooses, depending on the location on the body, the size and characteristics of the human body.

Let's stop in more detail on each method of treatment.

Removal of a nevus with a laser has many advantages. But you should know that this method is used when the diagnosis is made exactly and it is unambiguous. It is used to remove nevi that are on the face or neck. After the surgery, strictly follow the recommendations of the doctor to care for the wound so that there is no trace of it.

One of the most popular is considered radio wave removal method nevus Electromagnetic vibrations do not leave marks on the skin, scars or scars. And histology can be checked.

The method of cryodestruction means that a nevus will be affected by a very low temperature. It is used if the birthmark is in the hair growth zone or in hidden areas of the body. It is necessary to find an experienced specialist, otherwise you can get a scar or scar. As in the previous method, after surgery, histological examination is not possible.

Electrosurgery or electrocoagulation is also used to remove lesions on the skin. But it is not particularly common, since it is possible to get a scar in place of a nevus. That is, from an aesthetic point of view, this is not always acceptable. But you can hold histology examination.

A simple surgical intervention removes very large nevi.

There are, of course, folk methods of treating moles, but at first it will not be superfluous to undergo a full examination by a specialist.

What is papillomatous nevus?

A birthmark is a natural mark on the body, which appears in a person most often during infancy. It is precisely with this that the name of the neoplasm, which has become established among the people, is connected. For people who have a lot of moles on the body, the attitude is special. It is believed that the one whom nature has rewarded from birth with a large number of dark markings will be very happy in life.

But is it really, still a question, because moles (nevi) are not always a safe decoration, which sometimes promises not so much happiness as human tragedy. And the more moles on the body, the more cautious a person needs to be in life. He has to carefully protect the skin in places of localization of nevi from various injuries and active sunlight, regularly inspect it for changes in the shape, color or size of birthmarks and visit a dermatologist not once a year, but for any unusual changes in neoplasms.

It is especially hard for those who have prominent moles on their bodies, including papillomatous nevus. It must be said that this type of mole is a dubious ornament, most often found on the head and neck area. But its occurrence is also possible in other parts of the body.

A papillomatous nevus is a cellular structure that has an irregular convex shape and is not very pleasant in appearance. Such a mole consists of several elongated processes of the epidermis joined together and has a dense structure, since it is covered with a stratum corneum, consisting of melanocytes. Melanocytes (pigment cells) make the neoplasm even more noticeable, although its color can vary from solid to dark brown.

When viewed with a magnifying glass on the surface of a papillomatous (warty) nevus, you can see a lot of papillae, so its surface appears uneven, bumpy. Quite often, a dark brown bezel can be seen around such a mole, the surface of which is flush with the rest of the skin.

As we have said, papilloma nevus, resembling a strange complex wart, which is why it is sometimes called warty, is not very pleasant-looking education, which may cause fears of the owner of such a “decoration”, heard about the danger of degeneration of moles into cancer under called "melanoma". Therefore, many people ask whether a papillomatous nevus is dangerous - a neoplasm with such an unusual structure and an irregular shape, which is a worrying factor, because it is believed that a safe mole must have a regular shape and a symmetrical structure.

Doctors believe that by itself this type of mole, which can equally appear both at birth and throughout the person’s life, is generally not dangerous. This is a benign neoplasm consisting of normal, non-malignant cells, and if not injured, it will remain so for life. But precisely in this moment lies the hitch. Any convex mole has a greater chance of being injured than its flat relatives. And if, moreover, such a formation is located on the scalp, the risk of injury increases several times, because even the usual daily procedure of combing hair is a trauma to a nevus.

If a mole is located on the neck, it can regularly be rubbed with a collar, which is also considered to be small but traumatic. And if a nevus receives such an injury regularly, it can lead to a change in the properties of its cells, i.e. to their rebirth into malignant.

As you can see, papillomatous nevi due to its unsightly appearance can hardly be called a decoration, and the convex shape makes it not entirely safe due to the high risk of injury to the growth. It is for this reason that doctors often insist on the removal of such tumors, without waiting for them to turn into melanoma.

Causes of papillomatous nevus

Papillomatous nevus is one of the little-studied neoplasms on the human body. Doctors still fight over the reasons for its appearance to this day, but a proven final version has not yet been put forward. Studies are at the stage of hypotheses and the most logical, and therefore the most common of them was the version that the appearance of papillomatous nevi is one of the developmental disorders of the child in the embryonic period, i.e. in the womb.

There is an assumption that due to malfunctioning of the forming organs of the embryo, in certain areas of the skin there is a greater accumulation of melanocytes, which form a dark spot, which may have different color intensity depending on the amount of coloring pigment. Melanocytes form an intradermal nevus, which grows with the child’s body and can increase under the influence of certain factors, both during fetal development and after the birth of a baby.

As already noted, such moles are observed in children from birth. Just some of them are more visible, while other tumors are almost not visible. However, during the life of a person, nevi tend to increase in size several times, so at some point, even the inconspicuous earlier growth becomes visible.

Risk factors

Since we are talking about violations of embryonic development, there must be some reasons for such violations, because nothing in this world happens just like that, spontaneously. Risk factors for all sorts of failures in the emerging human body can be:

  • the exposure of a pregnant woman to ionizing radiation (for example, X-ray examinations, staying in a radioactive zone, regular prolonged exposure to the open sun, etc.),
  • all kinds of poisonings (food, chemical, medicinal, toxicoinfections) associated with intoxication of the mother's body, because toxins are transmitted by blood to the baby,
  • infectious lesions of the urogenital and other systems (pathogens also emit substances that poison our body, plus stagnation in the excretory system can provoke intoxication with our vital activity products),
  • hormonal imbalance with increased levels of estrogen in the blood of the expectant mother.

Enhanced growth of tumors in children and adults can be triggered by exposure to solar radiation (for example, a mole on the head can grow if a person does not wear hats that protect a nevus from sunlight), the use of potent chemistry in the home and at work, living in a high radioactive background, etc. But the growth of papillomatous nevus does not at all mean its degeneration into a malignant neoplasm or other complication, if no suspicious symptoms are observed (reddening, inflammation, appearance of necrotic sites, bleeding, etc.).

, , , , , ,

Papillomatous nevus is a neoplasm resembling a wart or papilloma in appearance. Quite often, such growths are found in newborns, which is not a cause for concern. But unlike conventional moles, the appearance of papillomatous nevi is not a warning sign in adulthood.

In fact, warty moles appear even at the birth of a child, they may first be invisible. But as it grows and rises above the skin, the neoplasm becomes more visible, and even more so when it is located on the face or neck. The man matures and the mole grows. Usually its growth stops after 30 years.

Papillomatous nevi, which may be intradermal or develop on the basis of intradermal formation, are considered benign and do not belong to the dangerous group with a high risk of rebirth. According to statistics, such moles very rarely turn into skin cancer, but since there is still such a danger, you should not forget about it. Moreover, melanoma, which develops at the site of localization of a once innocuous mole, can have a rapid development. And in this case, it is better to remove the often injured nevi in ​​advance and prevent the development of melanoma, than to try to cure a deadly disease.

Such growths on the skin often have a large size (from 1 cm or more). And large moles detected in infants have a 5% tendency to degenerate into malignant neoplasms. Yes, the risk is relatively small, but it exists. And when it comes to a disease that is difficult to treat and can cause a patient to die, even a small chance becomes a big danger.

Let's not frighten the reader, because the probability of malignancy of cells in the case of papilloma nevus is very low. Therefore, do not worry much if the tumor is just a cosmetic defect with a low risk of damage in everyday life. However, caution should be part of the patient's life, which will help prevent malignancy and other complications of wart nevus.

Symptoms of papilloma nevus

Externally, papillomatous nevus is not very similar to the usual mole. Instead of a nice dark speck, we see a hilly bump on a skin with a granular surface, resembling a papilloma on a thick leg (if we look at a mole under a microscope, we will also notice its resemblance to the fruits of mulberry).

But unlike the soft-touch papilloma, the warty nevus has a more dense structure and horny layer. In addition, most often such a tumor is pigmented, i.e. darker than other skin areas. Nevus flesh color is quite rare. Most often, tumors have a pink, brown or even a rare black tint.

Despite the irregular shape of the warty nevus has clear outlines and clear boundaries. Many of the nevi have a dark rim.

On the surface of such an unusual birthmark, it is often possible to find dark hair growing directly from a neoplasm and making it look like a fibroepithelial nevus.

Nevi with or without hairs can be located not only on the scalp. They can also often be found on the neck and face. More rarely, neoplasms choose armpits, skin areas under the mammary glands, groin area, etc., as their location.

As for the number of such neoplasms, they can be single or multiple, scattered throughout the body or located nearby in a limited area. And if these growths did not grow, the person would perceive them as ordinary moles.

But papillomatous moles tend to grow slowly and grow to large sizes, so on the body such formations look rather ugly, causing the owner of moles to become disheartened and even causing depression.

Papilomatous nevus - the formation of a non-inflammatory plan, so around it should not be swelling and redness. On the surface of a neoplasm that has a heterogeneous, nodular shape, however, there should be no purulent sores and bleeding cracks. The appearance of such symptoms may be the first sign of inflammation and infection of the nevus due to damage to the comb, collar, nails, etc., or indicate the development of a malignant process, which is much less common.

Various changes in it can tell about the malignancy of moles cells:

  • the nevus changed its color to darker,
  • cracks and inflammatory foci appeared on it,
  • the shape of the neoplasm has changed
  • the edges of the growth have become uneven and fuzzy,
  • dots of a different color appeared on the surface of the mole, dark foci of necrotic tissue, hair began to fall out (if they had been there before),
  • on the place of birthmarks appeared peeling of the skin, itching,
  • the mole has become painful,
  • other multiple tumors of irregular shape appeared (usually the papillomatous nevus grows up to 30 years of age, if similar tumors appear later, this is a reason to visit a dermatologist and conduct an appropriate examination, perhaps even with the involvement of more than one specialist).

It is necessary to understand that the rapid increase in any mole in size, the appearance of itching, swelling, pain, bleeding and other unusual symptoms is a pathological process, because nevi are considered non-inflammatory neoplasms, and for them this behavior is unusual. The appearance of such symptoms may indicate both damage and infection of the mole, as well as more sad consequences - the initial stage of melanoma.

Despite the low risk of transformation into a malignant neoplasm, any changes in the appearance and sensations at the place of birthmark should not be ignored. This will help avoid life-threatening complications.

So far we have been talking about papilloma nevus as a certain cellular structure towering above the patient's body. But it was mentioned that such moles may differ somewhat in appearance, which makes it possible to classify them, dividing them into separate types and forms.

Papillomatous intradermal nevus, or a growth of the verrucous type, is a formation strongly resembling a papilloma or a wart. It noticeably rises above the skin, but practically does not differ from it in color or has a light brown or pale pink shade. It has an inherent rough surface, often a mole consists of two or more lobes (several moles located in a small area tightly to each other). Such a mole grows very slowly, it inflames and bleeds in isolated cases, it is practically not prone to degeneration into a malignant tumor.

Papillomatous and verrucous nevi are not different types of moles. Wart nevus - This is one of the varieties of a Verrucous mole, which has a convex shape and a lumpy structure. Verrucous nevus may also be keratotic (very dense formation with a thick stratum corneum) or ichthyosiform, (growths similar to papilloma, sometimes have blisters on the surface, then they are called bullous).

Papillomatous melanocytic nevus - it is a pigmented type of convex neoplasm, which can have both intradermal and borderline character. Such moles often appear on open skin areas (on the neck, face, under the mammary glands, etc.) that are not covered by hair. Their color is determined by a large number of melanocytes in the middle and superficial layers of the skin, so the nevus can be either brown or almost black.

Melanocytes - cells that are found in large numbers on the surface papillomatous pigmented nevus, more prone to rebirth. Their presence in the upper layers of the skin makes these cells more susceptible to the negative effects of sunlight and mechanical trauma, which sometimes leads to the malignancy of nevus cells (albeit extremely rare). This is more common for border nevi with the localization of melanocytes in the epidermis.

The hair type of papillomatous nevus is characterized by the fact that one or several rather long hairs can be found on the surface of such neoplasms. Moles on which hair grows are considered completely safe. But if a person pulls out hairs growing in a birthmark, he will injure neoplasm cells, and they may behave in this case in an unnatural way. The situation when the hair on the mole falls out independently and no longer appears can indicate the development of melanoma.

This kind of as papillomatous mixed nevus sometimes called complex, since nevocytes (germ cells of a mole) can be located both in the middle layer of the dermis and at the border with the epidermis. If such a neoplasm consists of several nearby moles, then a part of the papillae on it may have a lighter shade. The surface of such a nevus is even more uneven.

In addition to various types of papillomatous nevus. There are also 2 forms of such neoplasms: organic and disseminated.

The organic (localized) form of the warty nevi is considered more common. In this case, it is a question of both individual neoplasms and several moles located close to each other in a limited area of ​​the body. Moles may be the same color or have different colors, up to bispigment or grayish. This form is considered safe due to the fact that it does not speak of any impairment of human health.

A desensitized (systemic) form is characterized by the appearance on the body of multiple pigmented nevi resembling warts. And there are moles on different parts of the body. This form does not always speak about the danger of impairment of health, but all of this quite often is evidence of serious neurological problems. Multiple moles can be observed on the body of patients with lesions of the central nervous system, and in particular with epilepsy.

Nevi in ​​systemic form may behave inadequately. For example, to grow throughout the patient’s life or to dry out and fall off without any influence on them from the outside.


Differential diagnostics

A large role in the study of patient moles is assigned to the differential diagnosis. Still, papilloma nevus has a certain similarity with many other neoplasms, and if injured, it can strongly resemble melanoma.

The wartan nevus has the greatest similarity with papilloma (hence one of the names of the mole). Papilloma is also a benign neoplasm, but the cause of growths on the skin is the papillomavirus, which for a long time can be in the body incognito.

The appearance of tumors in papillomatosis of the skin is not much different from papillomatous nevus. These are the same tubercles on a thick base (sometimes on a thin stem), which can be from beige to light brown. They can be localized in the grooved area and perineum, on mucous membranes, on the neck and eyelids, in the armpit. The size can range from tiny genital warts to growths about 2 cm in diameter.

What is different from papilloma papilloma nevus? Let's start with the fact that papillomatosis is an acquired disease that develops as a result of the virus entering the human body with its subsequent activation. Papillomatous nevus is a congenital neoplasm, which can become visible a little later as it grows.

The color of papilloma is usually almost the same as the color of a person’s skin, while a warty nevus can have various shades: flesh, pink, red, brown, purple, black.

The papillomatous nevus, although often with an irregular shape, is a symmetrical neoplasm with clear boundaries. For papilloma of such restrictions is not observed.

Inside a nevus a certain amount of melanocytes always accumulates, making the tumor more dense than the rest of the skin. Papilloma, on the contrary, is very soft with a gentle surface.

For papillomas on the skin, soreness, itching or burning are considered normal. Such symptoms on moles may indicate tissue damage, nevus cell degeneration, infection.

The pigmented type of papillomatous nevus has a certain similarity with the borderline pigmented nevus. It is a mole up to 1 cm in size with a bright shade (gray, brown or black) and a smooth surface. It is characterized by increased color intensity closer to the edge of a mole, lack of hairs, slow growth. It is also a congenital neoplasm, which, unlike papillomatous nevus, is considered to be melanohazardous.

Galonevus (or nevus Setton) also looks like papillomatous birthmark of the pigmented type. But this neoplasm has a distinctive feature — a rather broad rim of skin of a lighter shade forms around it. This bezel is noticeably lighter not only of the mole itself, but also of the rest of the human skin. It can be both single and multiple growths with a predominant localization in the back.

Galonevus as well as papillomatous nevus rarely develops into melanoma, but if there are many such tumors, it is likely that the patient will have other pathologies, such as an inflammatory thyroid disease (thyroiditis), which often causes hypothyroidism (organ failure), a violation of skin pigmentation , called "vitiligo", or hidden flowing skin cancer.

A papillomatous nevus of the pigmented type can be quite large in size and then it becomes like a giant pigmented nevus. The giant nevus is also considered to be a benign congenital neoplasm, but due to its size (20 cm in diameter), it is highly susceptible to trauma, which is considered to be melanophore. For example, in infants, in 5% of cases, the mole degenerates into melanoma.

Another bulging neoplasm that may have a thin or rather thick leg is called fibroepithelial nevus or fibropapilloma. These tumors are most often found on the face and body (especially with the armpits), but sometimes they are also found on the skin of the upper and lower extremities. This is a benign form of nevi, which can be both congenital and acquired, appearing at different ages.

The size of the tumor can vary from 2 mm to 2 cm, although there are larger growths. They have a spherical shape, a fairly smooth surface and soft to the touch. Possible growth of hairs on the surface of the growth. The color of fibropapilloma can also be different, but in general it is usually lighter than the pigment nevus. Most often, fibropapillomas are found on the face and body of the weaker sex.

A papillomatous nevus, which may have an irregular shape, somewhat heterogeneous color and different sizes, must be differentiated from a rare form of moles, called a dysplastic nevus. And although this form of neoplasm is diagnosed only in 4-5% of cases, it is considered quite dangerous and is close to a precancerous condition.

If the disease has a rare hereditary nature, then there may be several such tumors on the body. And even if some members of the family do not find moles of this type, they should still be regularly examined by a dermatologist, and if necessary, by an oncologist.

Acquired disease manifests itself usually single tumors (sporadic type). With papilloma nevus may be similar in appearance:

  • typical shape (tumor with an elevation in the center of various shades of brown in various shapes),
  • keratolytic form (growth that has a lumpy surface, light brown shade and large size),
  • erythematous form (large birthmark pink).

In contrast to the papillomatous nevus, the dysplastic form of moles, characterized by bizarre forms and uneven coloring, is very prone to cell malignancy and must be constantly under the supervision of a physician. Ideally, such moles are best removed immediately, without waiting for their degeneration into a cancerous tumor.

Papillomatous nevus in some cases may have a bluish or purple hue, which resembles a blue nevus (Yadasson-Tiche blue birthmark). Sometimes such neoplasms from blue to almost black can rise above the skin in the form of a nodule with a diameter of up to 1 cm (although there are instances 2-3 times larger). The favorite places of the blue nevus are the shin and forearm, hands and feet (back side), buttocks, but similar instances of moles can also be found on the face, neck, torso or in the lips.

The blue nevus is quite dense to the touch, but its tissues remain elastic and the surface is smooth. Hair on such moles usually do not grow. The papillomatous pigmented nevus is more similar to the cellular form of a blue mole with a dark color, rather large size and often an uneven surface.

Despite the fact that such neoplasms rarely turn into melanoma, they are considered melanohazardous and require regular monitoring.

We have listed only some of the tumors on the skin, with which it is necessary to differentiate the papillomatous mole. In fact, there are a lot more of them, and each can be fraught with a certain danger.

As you can see, papillomatous nevus is far from the only new growth of this type that can appear on the human body. And unlike a warty mole, some of them have a rather high risk of transformation into a cancerous tumor. The similarity of the tumor with others causes certain difficulties in the conduct of self-diagnosis, therefore, it is very difficult for a person far from dermatology to make a diagnosis. Such responsible work should be entrusted to professionals.

Treatment of papillomatous nevus

By themselves, papillomatous nevi are completely harmless tumors, if not caused by their discomfort and a high risk of injuring the mole, which will lead to changes in the properties of cells or infection of tissues. If the birthmark is located on the head, the person will constantly worry about what could be damaged during combing, washing the hair or cutting the hair. Nevus in the form of an ugly warts on the face will constantly call complexes from its owner about their external unattractiveness. Moles on the neck and armpits are subject to rubbing and irritation of clothing. Whatever it was, and there is inconvenience.

Treatment of papillomatous moles is their removal by an experienced specialist in the clinic. There are no other safe ways to solve the problem. Attempts to get rid of "warts" at home by cauterizing or bandaging can lead to disastrous results, nevertheless moles react to damage differently than normal warts or papillomas. In addition, there is always the risk of wound infection at the place of the former mole.

Removal of papillomatous nevus can be prescribed for several reasons. It is necessarily carried out if a rapid growth of a neoplasm was noticed, cracks and suppurating sores appeared on it, the place around the birthmark became inflamed and reddened. Itching, peeling, soreness of the growth can also indicate unhealthy changes in the cells of the nevus, so it will be better to remove the mole.

But even if the birthmark does not hurt and does not itch, but there is a high risk of its regular damage, a person can consult a doctor about the treatment of a neoplasm, and a specialist will necessarily meet it. As well as in the event that the mole spoils the patient's appearance, being located in places visible to the eye: on the face, neck, head. The possibilities of plastic surgery are such that even after the removal of large neoplasms on the body, an almost invisible scar remains, which looks much more aesthetic than some strange-looking moles.

Moles, the presence of which can cause depression and neurosis in their owner, are also subject to removal, even if they are considered safe.

Ways to remove a mole safely and almost painlessly great variety. This can be done with a surgical scalpel, laser, electricity, radio waves, cold. It is clear that the patient has the right to choose for himself which method is best to remove the neoplasm, but still it is worth listening to the opinion of the doctor, who will choose the best option based on the research and diagnosis.

For example, if a papillomatous nevus undergoes changes associated with cancer as a result of injury, the traditional surgical treatment would be the best method, when the mole is removed operatively with a scalpel. Such treatment will help to stop the spread of cancer, because not only patients are to be removed, but also a part of healthy tissues, where individual maling cells can be located.

Surgical removal of moles can also be prescribed for those patients for whom other more modern methods of treatment are contraindicated due to the existing diseases, the characteristics of the organism, the presence of metal implants, etc. The operation does not require the introduction of general anesthesia and anesthesia is applied topically.

The advantage of this treatment procedure is the complete absence of absolute contraindications and conducting it in a hospital setting by a qualified surgeon, and not in the cosmetology office or clinic where other methods of removing moles are practiced. There are, however, several relative contraindications to surgery, such as acute infectious and inflammatory processes, herpes sores on the body. The possibility of surgery during pregnancy and lactation will need to be discussed with your doctor.

A scar at the site of the former mole is considered to be a minus of surgery, especially if the tumor was large or melanoma developing on the site of a nevus was removed. Ugly scars will help to correct a small plastic surgery.

Laser treatment is considered to be one of the most popular innovative methods for removing various tumors on the skin and mucous membranes. It can take place both under local anesthesia, and without it, because the patient does not feel any tangible pain. The laser successively removes overgrown nevus cells.

The positive aspects of this treatment are: invisible scars and the absence of scars formed if the wound heals for a long time, bloodlessness (the laser removes the neoplasm and immediately coagulates the vessels and disinfects the wound), a small risk of inflammatory processes at the surgical site, a short recovery period with proper care wound. Laser treatment shows the best cosmetic effect (almost invisible scar remains), so it is recommended if the mole is located on the face or neck. But if there is no certainty that the tumor is benign, such treatment is not carried out, because it leaves no material for histology, despite the fact that only moles should be removed.

The disadvantages of treatment can be considered a higher cost compared with surgery. True, the result is worth it. And even if there is a scar on the skin, it can be corrected again with a laser.

Electrocoagulation is actually the burning of a mole by an electric current. Such treatment will be effective with small moles. Unlike laser treatment, after it there are tissues that can be taken for histology, and this can be considered a plus.

The positive aspects of the procedure can be considered the absence of bleeding, the possibility of under local anesthesia, the short duration of the operation and the recovery period, the absence of damage to healthy tissues. But the method has one big drawback: after the operation, noticeable scars may remain, therefore, no electrocoagulation method is used to remove moles on the face.

Cryodestruction or removal of a mole by freezing it also belongs to the category of innovative technologies. With the help of a special apparatus with liquid nitrogen, only the tissues of the mole are frozen. Low temperature leads to necrosis and death of nevus cells.

With all the effectiveness of the operation, doctors do not recommend it on open skin areas (on the face and neck), unless the operation is performed by a highly qualified specialist who can be trusted with such a scrupulous business. A doctor should calculate everything up to a millimeter, because too deep an effect of liquid nitrogen is fraught with the development of cold burn of tissues, which can cause the formation of an unaesthetic postoperative scar.

Cryodestruction is not used if there is a need to take a sample for further tissue research.

Radio wave removal of a papillomatous nevus is a very effective method of solving a problem that has many advantages. Among them are:

  • the almost complete absence of pain, which rejects the need for even local anesthesia,
  • minimum duration of the procedure (usually less than 5 minutes),
  • minimal risk of scarring,
  • the absence of such effects as tissue swelling, inflammation, wound suppuration due to infection.
  • very fast tissue regeneration after surgery, which gives the best cosmetic effect.

Radiowave method can be used to remove papillomatous nevi on any part of the body. The method does not lead to the destruction or death of cells, which means that the biomaterial can always be taken for histology.

As you can see, the removal of papillomatous pigmented tumors does not cause any particular difficulties and is available in almost any hospital (surgical method). But a person always has a sufficient choice of treatment options, which sin is not to use, if the birthmark interferes with normal life and to feel self-confidence and its attractiveness.

Moreover, the removal of moles is a universal method of treatment, regardless of what the cause led to such cardinal methods: inconvenience and lack of aesthetics of the neoplasm or its transformation into a malignant tumor.

General characteristics

Papillomatous nevus is a lumpy nodule, the structure of which includes papillary growths of a warty character. This formation is attached to the epithelium with a broad base. Most often, it is localized on the scalp, face, or neck. However, in some cases it can be seen on other parts of the body.

This form of a nevus, like most other types of moles, is included in the category of congenital formations. At the same time, the birthmark of a papillomatous character can remain imperceptible for a long time. However, this type of nevi gradually increases and reaches its final size in 20-30 years.

Such moles are benign in nature and do not pose a health hazard. However, in medicine, there are rare cases when such a nevus has transformed into melanoma.

It should be borne in mind that this convex mole gives a lot of inconvenience. Since in most cases it affects precisely the head, there is a high probability of damage when combing, dressing or washing the head. This increases the risk of nevus degenerating into a malignant tumor or the development of the inflammatory process.

Experts for many years engaged in the study of the mechanism of development of this benign education. However, the exact reasons for its appearance still remain controversial. Currently, the most reliable version is a congenital disorder of intrauterine development.

The most common causes of fetal defects include the following:

  • exposure to increased doses of radiation,
  • long stay in the sun
  • contact with chemicals
  • ingestion of toxic fumes.

Differences papilloma from nevus

To distinguish a mole from papilloma, it is recommended to contact a dermatologist. Only a specialist can accurately determine the nature of the formation on the skin. Nevertheless, a person can make a preliminary diagnosis independently, relying on the following features:

  1. Moles can occupy the whole part of the body or can be literally a few millimeters in size. In this case, papilloma usually reaches 2-15 mm, increasing to 5-6 cm only in case of damage.
  2. Nevi have a firm and dense structure, whereas papillomas have a loose consistency and are soft to the touch.
  3. The basis of moles are the skin cells, and the papilloma consists of blood vessels.
  4. Birthmark is a feature of each person, in some cases, birthmarks are inherited. At the same time, dissemination of papillomas is carried out exclusively by infectious means - through household and sexual contacts.
  5. Nevi can have various shades - pink, light, black, brown and even bluish. Papillomas are always painted in a light color - solid or pink.
  6. Moles can affect any part of the body, including mucous membranes. The main area of ​​localization of papillomas is the mucous membranes and areas of strong friction.
  7. Moles must have a smooth symmetrical shape - round or oval, while papillomas may have different outlines.
  8. Nevus appears at birth or in the first years of life. Papillomas develop several months after infection. Rapid formations can occur after 1-2 months, and prolonged - after 4 months.

The papillomatous nevus has a number of characteristic symptoms:

  1. The mole has a convex structure and resembles in its shape a tubercle that protrudes above the skin surface and is attached to it with a wide leg.
  2. The integumentary epithelium has a thickened character. At the same time the mole is quite dense to the touch.
  3. In most cases, papilloma nevus has a bumpy surface and granular structure. It is based on elongated epidermal processes. This can easily be considered during microscopic examination.
  4. The tumor has clear boundaries that have an arbitrary shape.
  5. Papillomatous nevus can have different shades - there are bodily, brown, brown formations. Black moles are sometimes observed. This is determined by the amount of melanin that is present in the cells.
  6. Birthmarks can be single or multiple.
  7. The size of this education is quite impressive - from 1 cm.

Papillomatous nevus of the scalp

In most cases, this formation affects the scalp. However, it is sometimes detected on other parts of the body. Papillomatous nevus has irregular contours and different shades. Sometimes it can be very pigmented - brown and even black.

Treatment and removal of papillomatous nevi

As a rule, such moles are recommended to be removed with constant injury, the appearance of psychological discomfort or the development of inflammation. If, as a result of diagnostic studies, it was not possible to completely eliminate melanoma, it is also recommended to remove a nevus. At the same time, histology of education is performed.

Various methods are used to remove this type of mole: laser, radio wave exposure, cryodestruction, electrocoagulation. Surgical excision may also be performed. In any case, shows the use of local anesthesia.

If a papillomatous nevus is localized to the neck or face, laser removal is usually used. If you properly care for the wound after surgery, you can achieve the best cosmetic effect. However, in doubtful cases, this intervention is not carried out, because it does not provide an opportunity to obtain material for histology.

The use of cryodestruction to remove such formation is indicated when localized on the scalp or areas that are usually hidden by clothing. This technique can be used exclusively by qualified professionals. This is due to the fact that the deep effect of liquid nitrogen on the skin provokes a cold burn and leads to the formation of a scar. Conducting histology in this case is also not possible.

Excellent results can be achieved using radio wave removal method. After this procedure, the tissue is completely healed without scarring. This allows you to achieve excellent cosmetic results. At the same time, a remote nevus can easily be sent for histology.

Electrocoagulation of a nevus is used quite rarely, since after its conduction a noticeable scar is usually formed. However, after this procedure, histological examination can be carried out without problems.

Papillomatous nevus in children

The appearance of papillomatous moles may occur after birth. This formation is not life threatening if the pigment does not change the properties and the mole is not exposed to damage.

With constant injury and bleeding education should consult a doctor who can decide on the removal of a nevus.

Papillomatous nevus in pregnant women

To prevent negative health effects, pregnant women should avoid exposure to negative factors. These include:

  • radiation,
  • effects on the body of toxic substances,
  • a significant change in the hormone content
  • infectious lesions of the urinary system.

The appearance of papillomatous nevus can cause a person serious discomfort, especially since such formations are often in prominent places. In such cases, the removal of moles. If education does not bother the person, you can not touch it. But in any case, the slightest changes in the structure of the nevus should be the reason for the visit to an experienced dermatologist.

What is and the code for ICD 10 papillomatous nevus

In papillomatous nevus code ICD-10 does not exist, it is a benign skin formation.

The color of the sprawl is different. Some have a brown or brown tint. There are flesh-colored elements. Inside can pass pigmented hair.

The accretions are arranged singly or in groups. Characteristic features of specific moles include:

  1. Slowly grow.
  2. Favorite localization - armpits, head, neck, groin area.
  3. Formed in the prenatal period, adolescence.
  4. May be invisible at first. Gradually increasing. Formations of large sizes significantly complicate the life of the patient. Holder marks easily hurt her. If the growth is located on the scalp, the damage occurs comb, nails.
  5. The bumpy mole is inherited.
  6. Outgrowths rarely malignant. The main cause of malignancy is damage.

Why is a nevus called intradermal papillomatous

Intradermal papilloma nevus is a cellular structure consisting of islands of the epidermis of an elongated shape. The nest has a dense consistency due to the upper stratum corneum. It contains melanocytes. Pigment cells provide a dark color element. The bumpy surface is created by numerous nipples that can be distinguished under a magnifying glass.

Often around the wart is a bezel of black or brown color. It does not rise above the skin.

According to the international classification, there are several types of moles:

  1. Verrucous type looks like a normal wart. Education is light brown, pink, flesh-colored. It has a bumpy surface, lobular structure (2-3 moles, which are closely adjacent to each other). Verrucosis element rarely bleeds, not prone to malignancy.
  2. Melanocytic nevus - convex growth with intradermal or border growth. Localized in the neck, face. Anger is a serious danger. May degenerate into a malignant tumor.
  3. The hair type of a specific mole differs from other formations by the presence of a long hair on its surface. Periodic pulling of hair leads to trauma to the melanocytes. Damaged cells are reborn into a malignant tumor.
  4. Mixed or complex type refers to the abnormal development of the skin, has a complex structure. Germ elements are located in two layers of the skin: intradermal, border. The nest consists of many papillae of different sizes. Education grows to 10 mm. Mixed nevus doctors try not to disturb.

Disseminated incrustations are brown plaques that are localized near the nerve trunks, large vessels. Sprawl periodically disappear on their own, then grow back. The appearance of disseminated elements indicates the pathology of the nervous system. Patients should be monitored by a neurologist.

Separately worth noting the classification of the risk of malignancy. Allocate melanoopasno, melanomoneh elements. In the first case, the risk of rebirth is high, in the second - minimal.

Is HPV a cause of nevus?

Intradermal papillomatous nevi in ​​appearance resemble papillomas. The appearance of the melanocyte element is not associated with the papillomavirus. Two similar skin growths differ in etiology, structure. Papillomatosis (ICD-10 code D 23) is a chronic infection triggered by HPV activity. Pathology affects children, adults. The main route of transmission of the virus is contact-household, sexual, and intranatal.

Melanocytic papilloma intradermal warty nevus is formed by melanocytes. The causes of the appearance on the human body are not fully understood. There are several theories of origin:

  1. According to the first theory, education is transmitted along the family line. Confirms the fact of a similar localization in parents, children.
  2. The second theory is based on the excess secretion of melanin. Melanocytes accumulate under the skin in one place, begin to intensively highlight the coloring pigment. Active production of melanin occurs under the influence of ultraviolet radiation.
  3. According to the third theory, intradermal growth occurs in the prenatal period. They provoke the emergence of hilly formations destructive habits of the mother, inflammatory diseases, contact with harmful substances.
  4. The fourth theory connects the occurrence of growths with hormonal disorders. Melanocyte-stimulating hormone of the pituitary activates melanocytes, which begin to synthesize melanin.

Similar and different features of papilloma nevus and papilloma

Similarity is manifested in the following points:

  1. Have a bumpy surface, large size, painted in brown.
  2. Belong to benign elements.
  3. Rarely malignized.
  4. Not manifested by severe clinical symptoms.
  5. Easily injured.

The differences between this type of nevi and papilloma are in the following points:

  1. Different structure, causes.
  2. Papillomas regress under the influence of drugs, folk remedies.
  3. Melanoform moles are more often localized on the scalp and neck. The favorite location of papillomas is the groin area, back, palms, and feet.

The main task of the doctor is to conduct a differential diagnosis.

Should I treat melanocytic papillomatosis intradermal nevus

Melanocytic outgrowths of the skin do not need treatment if they are asymptomatic.

It is recommended to consult a dermatologist in the following situations:

  1. Education has rapidly increased in size.
  2. There was pain, burning, itching.
  3. The growth is located on the leg, often injured.
  4. Darkening may be due to its malignant degeneration. Change the color of moles - a direct indication to consult a doctor.
  5. There is a strong peeling, visible erosion.
  6. Head localization increases the risk of mechanical damage to the element. A person breaks integrity when combing or cutting hair. Damaged melanocytes can regenerate into atypical cells. Over time, melanoma occurs. Injured growths should be immediately indicated to dermatologists.
  7. The appearance of bleeding, purulent discharge from a mole requires immediate medical advice.

The dermatologist will examine the papillomatous element, determine the further treatment tactics. The doctor will prescribe general clinical blood tests, necessary additional research. After a detailed diagnosis, obtaining the results of surveys, the question is raised about how to get rid of the formations.

There are several removal methods:

  1. Surgical treatment is used to combat various skin growths. The surgeon cuts out moles with a scalpel under local anesthesia. The resulting material is sent for histology. Experts make a microdrug, which is examined in detail under a microscope. After the operation, there remains a small wound, which quickly heals. A scar is formed on the site of the former nevus. At the present stage of development of medicine there are non-traumatic methods of treatment.
  2. Cryodestruction removes skin growths with liquid nitrogen. Substance freezes cellular elements. Blood circulation and metabolic processes inside the mole stop. It dries out. The medical event is held on an outpatient basis. The procedure takes from 5 to 20 minutes. Element disappears in 2-3 days. An important feature of the method - does not cause bleeding, does not leave scars.
  3. Laser removal is a modern way of getting rid of papillomatous growths. The laser painlessly burns education. There remains a small cavity, which is quickly tightened. Laser destruction is never complicated by bleeding, it does not lead to the formation of keloid scars.
  4. Radio wave surgery is based on the action of a radio wave knife.
