Urothelial carcinoma of the fossa navicularis successfully treated with laser ablation and distal urethrectomy: A case report.

Primary urothelial carcinomas very rarely arise from the fossa navicularis of the penis. They are rarely reported in the literature, with only 13 cases reported thus far. Herein, we present the case of a 34-year-old man with bloody urethral discharge due to a mass detected by cystourethroscopy in the fossa navicularis.
