Bowenoid papulosis and squamous cell carcinoma of the genitalia: suspected sexual transmission.

The human papillomavirus causes a variety of genital lesions: condyloma acuminatum, bowenoid papulosis (carcinoma in situ), and squamous cell carcinoma. Only condylomata have been documented to be sexually transmitted. We report clinical and histopathologic evidence of suspected female to male transmission of bowenoid papulosis to the penis from a woman with condylomata acuminata, squamous cell carcinoma in situ, and focally invasive squamous cell carcinoma of the vulva. These findings indicate a need for thorough clinical and histopathologic evaluation of any anogenital lesions resembling condylomata and occurring in sexual partners. Conservative yet thorough destruction of bowenoid papulosis and squamous cell carcinoma in situ appears to be the treatment of choice.
