Nevi on Genital Skin

  • Guido Massi
  • Philip E. Leboit


The majority of nevi situated on genital skin (and on other hormonally-affected skin regions) has no peculiar histological characteristics (or have the architectural features of a Clark or dysplastic nevus). This is especially true in post-menopausal women. A few of them, especially in younger women show important cytological and structural findings that can simulate melanoma, leading to inappropriate resection in areas in which conservation of tissue is especially important (Friedman). Nevi on the vulva are much better described than are nevi on male genitalia. This is probably due to the different ages at which genitalia are examined by doctors. Young women are subject to examination at routine gynecologic visits and by obstetricians, while the genitalia of men are not usually scrutinized until they visit urologists in late middle age (at which point many of their nevi have faded).
