Department of Urology, National Chiba Hospital.

We report a case of papillary adenoma of the prostatic urethra composed of prostatic-type epithelial tissue. The patient was a 48-year-old male with complaint of urethral bleeding. Tumor was transurethrally resected. Sixty one such cases (males, 17-82 years old) have been reported in Japan. Of these patients, 31 (51%) were between 30 and 49 years old, the mean age was 43.9 years old. The lesion was located on the verumontanum (20%) and around the verumontanum (80%). The general symptom was hematuria (65.6%) and sometimes hemospermia (11.5%), dysuria (9.8%). Cautious fulguration was generally performed and the recurrence was reported in 4 cases (6.7%). It is believed to be a completely benign lesion, since no cases of malignant transformation has been reported. However, we must note that 3 cases (4.9%) had a malignant tumor in the lower urinary tract (bladder 1, urethra 2) at the same time.

D014523	Urethral Neoplasms	Cancer or tumors of the URETHRA. Benign epithelial tumors of the urethra usually consist of squamous and transitional cells. Primary urethral carcinomas are rare and typically of squamous cells. Urethral carcinoma is the only urological malignancy that is more common in females than in males.
