Vulvar neoplasia in the young.

Vulvar intraepithelial neoplasms may be occurring more frequently among younger age groups. Six patients with carcinoma in situ or severe vulvar dysplasia are reported, as well as one patient with microinvasive carcinoma, all under the age of 30 years. The vulvar lesions were noted to be mostly multicentric. They were associated with other intraepithelial neoplasias of the cervix or vagina in four of the six cases. The lesions were most often mistaken for condyloma acuminatum. Histologic changes were primarily Bowen's disease or Bowenoid dysplasia.
