膀胱腫瘍と診断された異所性前立腺ポリープの1例

Abstract

We report a case of ectopic prostatic polyp preoperatively diagnosed as bladder tumor. Several examinations highly suggested the possibility of a bladder tumor invading prostatic tissue, but the exophytic lesion was located proximal to the verumontanum. Transurethral resection of the lesion was performed, and the histological examination revealed typical findings of benign prostatic hyperplasia. We reviewed 42 cases of ectopic prostatic tissue reported in the Japanese literature. Ectopic prostatic tissue should be considered in the differential diagnosis of hematuria in the male.
