[Condylomatous carcinoma of the urethra that detected human papillomavirus type 16 genome: a case report].

This is a report on a rare case of male urethral condylomatous carcinoma that detected human papillomavirus type 16 genome (HPV16). He had been administered immunosuppressant, since he had a kidney transplant in 1977. Papillary tumors spread from the external urethral opening to the membranous urethra. Histologically, the tumors presented papillary growth and koilocytotic atypia on the surface part. Moreover, we observed corpus spongiosum penis invasion and vein invasion, and detected HPV16 by immunostaining. We diagnosed condylomatous carcinoma. We treated with anterior urethrectomy and cystostomy.
