title: Villous adenocarcinoma of the male urethra.
abstract: We report on 2 men with multifocal papillary adenocarcinoma arising in the bulbous urethra proximal to a urethral stricture. Histologically, the tumors appeared similar to villous adenocarcinomas of the colon and rectum. Both patients were treated with segmental urethrectomy. Villous adenocarcinoma of the male urethra is a distinctive clinicopathologic entity. Although uncommon it should be added to squamous cell carcinoma and transitional cell carcinoma on the list of tumor types causing cancer of the male urethra.
