Nevus skin

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.

Nevus: normal

  1. 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.
  2. In childhood, neoplasms may be imperceptible, but during puberty, under the influence of UV rays or during pregnancy, they usually appear sharply.
  3. 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.

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.

Gradually the birthmark lags behind the skin and keeps on a thin stalk. Sometimes such a neoplasm turns into a warty nevus.
