Benign Melanocytic Nevus

Article

A variety of benign lesions in elderly patients involve proliferation of melanocytes. These lesions include dysplastic nevi, which histologically contain somewhat asymmetric nests of melanocytes; compound nevi, which histologically contain more symmetric nests of melanocytes in the dermis and epidermis and intradermal nevi, which histologically contain nests of melanocytes in the dermis.

A variety of benign lesions in elderly patients involve proliferation of melanocytes.1,2 These lesions include dysplastic nevi, which histologically contain somewhat asymmetric nests of melanocytes (A); compound nevi, which histologically contain more symmetric nests of melanocytes in the dermis and epidermis (B); and intradermal nevi, which histologically contain nests of melanocytes in the dermis (C). Melanocytic nevi do not require removal unless a melanoma is suspected.
