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.
