A-24-year old man was referred to our hospital for further examination and treatment of a papillary tumor protruding from the urethral meatus. He noticed the tumor two weeks after the recent sexual act. The lesion extended from urethral meatus to the fossa navicularis,but no remarkable findings were found in the bladder,posterior urethra,foreskin and glans. The tumor was resected completely and histological diagnosis was condyloma acuminatum. The HPV-DNA in the excised specimen was examined by liquid hybridization assay and types 6,11,42,43 and 44 were positive. There has been no recurrence of tumor for three manths after surgery.
