[Transitional carcinoma of the prostate. Report of a case treated with chemotherapy]

A case of transitional cell carcinoma of the prostate is described which had been diagnosed following TUR of the prostate due to cervico-prostatic obstruction. Subsequent cystoscopic and cytological controls, as well as multiple bladder biopsies have discarded a concomitant urothelial tumor. We underscore the rarity of transitional cell tumor of the prostate, its response to chemotherapy and the possibility of suspecting this tumor type when there is massive invasion of the prostate following TUR.
