Clinical and Histopathological Characteristics of Genital Melanocytic Nevi: A Report of 109 Cases and a Review of the Literature

Melanocytic lesions on the genital area are rare and poorly documented; they occur more frequently on the vulva and less often on the perineum, pubic area, and male genitalia. Genital melanocytic nevi exhibit features similar to nevi occurring on other areas of the body; in addition, they display high clinical and histopathological variability and are mostly classified as common nevi. However, a benign subtype of genital nevi that occurs in young women is known as atypical melanocytic nevi. These nevi exhibit distinct morphological characteristics that sometimes overlap with those of cutaneous melanoma.
