[Transitional cell carcinoma of the urethra in a male]. / Carcinoma transicional de uretra de un varón.

We present a case of primitive urethral carcinoma in a male. The diagnosis was established with physical exploration when we observed papillomatous formations in the fossa navicularis upon everting the meatus. The interest of this case lies in the rare nature of primitive urethral tumours, in its localization at anterior urethra level, and in its transitional histological strain, as transitional ones are usually located at prostatic and not anterior urethra level as in this case that we submit.
