HPV infections of the lower genital tract are associated with the increasing incidence of vulvar intraepithelial neoplasia. The new classification divides vulvar intraepithelial neoplasia according to its incidence into two groups: usual and differentiated type. The usual type occurs mainly in young women and is associated with HPV infection, the differentiated type is HPV-negative and occurs in older women. The diagnosis is based on biopsy from a suspicious lesion. The standard treatment involves surgical excision. Topical treatment is now being preferred in young women in order to preserve appearance of the genitalia and sexual function. The high risk of recurrence is the reason for strict monitoring of patients after treatment completion.
