男子尿道乳頭腫の2例

Abstract

Two cases of benign papilloma in the male urethra are reported herein. The first case was a 27-year-old man who complained of miction pain. A pea-sized papillary tumor was found in his external urethral meatus. Urethrocystogram revealed no abnormal findings. He was treated with simple excision and electrofulguration of the tumor and experienced no recurrence of the tumor up to now. The other case was a 24-year-old man who complained of tumor-formation in his distal urethra. Three papillary tumors as large as a grain of rice or a pea were found in his fossa navicularis, besides on panendoscopic examination, a small papillary tumor was found on the bulbous urethra. After he was treated with simple excision and electrofulguration of the tumors on the distal urethra, no tumors were found in his whole urethra on panendoscopy. He also experienced no recurrences of tumor to date. Histologic examinations of both cases revealed squamous papilloma of the urethra. There are a few reports of benign tumors of the male urethra in the Japanese literature. Of them, 48 cases of urethral papilloma in male were collected and are reviewed herein.
