膀胱腫瘍によるmalignant priapismについて

Abstract

A 72-year old man was first seen with asymptomatic gross hematuria on 17th, March, 1975. Cystoscopy revealed a sessile tumor on the vault. Total cystectomy and ileal conduit was performed on 7th, April, 1975. Seventeen days after the operation, induration (7cm long× lcm wide) developed in the dorsal plateof the penile shaft, which rapidly extended and caused so-called "malignant priapism". The corpus cavernosum was biopsied on 16th, July, 1975. This showed a well differentiated transitional cell carcinoma. Two weeks later, total penec(omy was performed. Now, 11 months after the second operation, he is alive. Some reports on malignant priapism predict poor prognosis of such cases. Several literatures on malignant priapism secondary to the bladder tumor in Japan were reviewed and discussed.
