First, pigmented nevus can be divided into three types according to pathological examination, namely, junctional nevus, mixed nevus and intradermal nevus. Junctional nevus is flat or slightly higher than the skin, with smooth surface and no hair. Its nevus cells and nevus cell nests are mainly located at the junction of the epidermis and dermis of the skin. Therefore, the name is given. The nevus cells of junctional nevus have the characteristics of active proliferation and have the chance of malignant transformation. Intradermal nevus is flat or higher than the skin, with uniform color. Sometimes one or several hairs can be seen in the center. It is the most common pigmented nevus in adults. The nature of intradermal nevus is relatively stable, and there is no malignant change in clinic.

The central part of the nevus is a plaque protruding from the skin surface, often with hair, surrounded by smooth halos with diffuse pigment distribution. The nevus cells and nevus cell nests of mixed nevus are found in both the deep epidermis and the dermis. Due to the existence of borderline vitality, it is also possible for malignant transformation.
