A nevus (birthmark or birthmark) is a benign tumor that forms on the surface of the skin. It can develop from the elements of the epidermis or from the dermis itself.
- As a rule, nevi are found in 80% of Caucasians. On the body of an adult on average there are about 20 moles. In some people, the number of birthmarks can exceed a hundred.
- In childhood, neoplasms may be imperceptible, but during puberty, under the influence of UV rays or during pregnancy, they usually appear sharply.
- Nevus has several phases of development. At first it is intraepithelial, then it goes to the borderline, and at the age of 30 it becomes intradermal. When a person crosses an elderly period, moles often undergo a reverse development: gradually, a nevus can sink into the skin, being replaced by skin tissue.
Nevus skin: species
Most tumors are congenital or acquired. They have several varieties that are distinguished by their development and education.
- Pigment nevus
It has the appearance of a mole and rises above the skin. As a rule, it can be located on any part of the body and has a different color (from light brown to black). On the pigment nevus grow hard and black hair. This is its main distinguishing feature.
- Dysplastic nevus
This is an acquired neoplasm, which is formed due to the indiscriminate division of atypical melanocytes. Such moles are found in 5% of the population and develop on healthy skin from complex nevus. The appearance of such tumors contribute to the sun's rays. It is not characterized by spontaneous extinction. Outwardly, such a mole looks like a spot with separately elevated parts above the skin. It has a fairly large size - more than 15 mm and uneven color. Asymmetry, fuzzy edges and jagged edges are typical.
- Papillomatous (warty) nevus
It looks like a papilloma and has a large size. Usually, such a tumor is formed on the head or neck, but may also be found on other skin areas. Often you can see growing hair on it.
- Non-cellular border nevus
This is a permanent spot that may protrude above the surface of the skin or not rise at all. This mole has a clear border and brown color. It can have different sizes and be on any parts of the body.
- Intradermal nevus
This is the most common type of melanoid nevus. The accumulation of pigment cells is located in the middle of the middle layer of the dermis.
- Intradermal nevus
He stands above the surface of the dermis and has an uneven surface. Habitual habitat - head or neck, rarely - the body. This type of neoplasm appears between the ages of 10 and 30 years. Gradually the birthmark lags behind the skin and keeps on a thin stalk. Sometimes such a neoplasm turns into a warty nevus.
- Blue Nevus
It has a blue color, small size (no more than 5 mm) and is characteristic of Asian nationalities. Rises above the skin, has a smooth surface and quite dense to the touch. On this mole never grow hair.
- Basal (pigmentless) nevus
It has no color, so it is difficult to detect. It looks like a normal mole.
- Nevus Becker
As a rule, it is formed in young men of 10 - 15 years. First, a few brown spots appear on the body. Spots are located next to each other. Gradually, they merge and form one large spot with vague contours, up to 20 cm in diameter. With time, the stain turns into an uneven warty surface covered with hair.
- Linear nevus
The tumor, which is a lot of small patterns of different colors. Located on the skin in the form of a chain and appears from birth. It may be small or spread throughout the body. Sometimes hair grows on it.
- Vascular nevus
This is a stain painted in red or pink. If such a nevus is located on the back of the head or on the forehead, with age it may turn pale and eventually become imperceptible.
