title: Papillary prostatic epithelial hyperplasia of the urethra: a cause of hematuria in young men.
abstract: We describe 4 cases of gross hematuria in young men due to papillary urethral lesions composed of prostatic-type epithelium. The clinical presentation, cystourethroscopic and pathological findings, and management are reviewed. A possible histogenesis is proposed based on a comparison of surgical biopsy tissues from 4 cases with prostatic urethral sections of 8 autopsy cases with no known genitourinary problems.
