Dysplastic nevi - characteristics
 Nevus (birthmark, mole) - is a benign skin lesions, is a collection of novotsitov that contain melanin pigment in large quantities. The word comes from the Latin "naevus", which translates as "a mole."

There are many different types of birthmarks, which include congenital (visible from the first days of life the baby) and acquired (appearing later). The classification of these entities is extensive. Let us examine three common types of nevi: intradermal, papillomatoznyh and dysplastic, although in fact there are many more.

Intradermal nevi

This variety of moles, usually congenital, and does not turn into a malignant neoplasm, ie is melanomoneopasnoy. According to the histological data of intra dermal nevus can give rise to the primary melanoma is extremely rare.

Until now know the exact cause of this type of birthmarks, however, there is the hypothesis that they are the result of genetic disorders.

Intradermal education have a domed or warty appearance, sometimes located on the "leg" and is shaped like a blackberry. Their color can vary from light shades of brown to completely black. The size is usually not more than a few centimeters.

Intradermal nevi can be single or multiple, and is most often on the face or neck, in rare cases, appearing on some other areas of the skin. As the formation of the body is also increased in size.

Among the possible complications, except for the risk of degeneration of a mole into melanoma, there is a risk of its mutation in papillomatous nevus. As a result, in it there are many irregularities, crevices and folds, which accumulate pathogens and dead cells, which is fraught with the development of an infectious process.

Papillomatous nevus

It is benign, which acts on the skin and looks like papilloma. In most cases, papillomatous nevi located in the scalp, and may be either congenital or acquired. Since the risk of transformation into melanoma is extremely small, this type of birthmarks related to melanomoneopasnym.

The cause of education are the genetic characteristics of a person, so that there is accumulation of pigment cells in one place.

Papillomatous nevus has a bumpy surface, and irregular shape, rising above the level of the skin and can be covered with hairs. Its color is brown or brown, and sometimes it does not differ from healthy skin. Education is a single or multiple and can reach very large sizes.

Dysplastic melanocytic nevi

Dysplastic nevi, often called atypical birthmark, is a precursor to cancer - melanoma. The frequency of detection is the same for both sexes. Appearing in 12-15 years, moles continue to act on the body to a ripe old age, leading to the formation of new spots.

Individual perception of UV rays, sex and age of the person does not have any effect on the appearance of dysplastic melanocytic nevus. Such formations are inherited autoimmune channel, and with excessive exposure to artificial ultraviolet light or sunlight, they degenerate into melanoma. The risk of transformation of benign dysplastic nevus to a malignant tumor in patients who are taking immunosuppressive drugs.

A typical feature of education is its dual structure. Melanocytic nevi has the form round spots on the skin with a raised central part. The color scheme varies from red-pink to black and brown. The size of moles reaches 5 mm, and their boundaries are blurred.

Education, as a rule, plural, suggesting that the dysplastic nevus syndrome. Most spots are located in areas of the body that are closed from the sun - the scalp, back, lower extremities, chest, buttocks and genitals. Very rare melanocytic nevus appears on the face.

Treatment nevi

Health and Beauty offer several different types of ways to remove moles.

The most accessible and popular treatment for nevi - resection conventional surgical scalpel. However, this operation has both pluses and minuses. The main drawback - the probability of occurrence of scars. In addition, the procedure is quite painful, and therefore requires the use of local anesthesia or general anesthesia. However, in some cases, for example, malignant dysplastic nevi, such treatment is most effective, and sometimes the only possible one.

Another way to remove moles - is cryotherapy. This method of treatment nevus exposed refrigerants such as dry ice or liquid nitrogen. Under the influence of low temperature nevotsity freeze and die.

 Nevus - removal methods
 Kriolechenie opposite way to get rid of moles - electrocautery, which is cauterization of pigment cells. The operation is painful and is done under general anesthesia. The main advantage of electrocoagulation is that it is virtually bloodless.

There are less traumatic treatments nevi, such as laser ablation, the benefits of which are obvious: the operation is painless, does not require anesthesia, is fast and does not leave scars or scars.

A promising method is a cosmetic point irradiation, but if there is a risk of degeneration moles in melanoma, it can not be used.

To prevent transition normal skin defect in a dangerous disease is quite simple. To do this, you must take responsibility for their own health and the state of the skin, especially in the field of localization of moles, as well as to comply with preventive measures.
