Multicentric bowen's disease of the genitalia: spontaneous regression of lesions.

The phenomenon of multiple lesions of Bowen's disease appearing on the genitalia of young adults is becoming increasingly recognized. We have seen two patients who had genital lesions with histologic features of squamous carcinoma in situ, but with an entirely different clinical appearance. In both patients, varying degrees of spontaneous regression occurred. A conservative approach to management of these lesions is suggested.
