Prospective study of vulvar nevi.

We report the results of a year-long prospective study to approximate the prevalence of pigmented lesions of the vulva in a gynecology practice. A total of 301 new patients were screened during their routine gynecologic examination. Thirty-one (10.3%) had pigmented lesions in the vulvar region, and an additional six (2%) had diffuse hyperpigmentation. Only seven patients (2.3%) had vulvar nevocytic nevi.
