[Obstruction of the prostatic urethra by villous adenoma].
We report a case of a benign villous adenoma of the prostatic urethra causing urethral obstruction in a 45-year-old man. Villous adenoma of the prostatic urethra is rare. Hematuria was the presenting sign in most reported cases. However, some lesions were discovered unexpectedly on endoscopic examinations for the assessment of lower urinary tract disease. Villous adenoma of the urethra is composed of prostatic type tissue. The presence of the PSA marker in its epithelium indicates a common embryologic origin with the prostate.
