Intraepidermal, or borderline nevus is one of the many varieties of nevus, which has its own distinct characteristics and features. This neoplasm is small, but quite dangerous: it has a tendency to overgrow and malignancy.
Moles, or nevi are available to all. These are benign neoplasms of different shades of brown color. Their color is provided by melanin, a pigment found in melanocytes (skin cells), of which nevi are composed.
Convex birthmark (nevus) is a benign neoplasm on the skin. From the point of view of dermatologists, moles and birthmarks have similar medical causes. At the initial stage of development the mole looks like a small speck of dark color on the skin.
On the body of each person there are birthmarks. In many cases, these are innocuous entities related to an innate or acquired phenomenon. Benign moles can appear throughout the life of a person. They must be carefully monitored and not allowed to be mechanically damaged.
