Transitional cell carcinoma in the fossa navicularis of the male urethra: a case report

We report a case of transitional cell carcinoma arising in the fossa navicularis of the male urethra. The patient was 87-years-old and noticed intermittent urethral bleeding. We could see a tumor protruding from the urethral meatus, removed it successfully, and irradiated the base of the tumor with Nd:YAG laser. The histologic finding was grade 2 transitional cell carcinoma, pTa. There was no other tumor in the urinary bladder or upper urinary tract. The postoperative course was uneventful and the patient showed no evidence of disease for 4 months after treatment but died from other causes.
