Benign Prostatic Epithelial Polyp of the Urethra

Abstract

Acquired polyps of the male urethra often present with hematuria and sometimes hemospermia. The histogenesis of these tumors has been debated. We report a case of a prostatic urethral polyp that proved to be of prostatic epithelial differentiation, as demonstrated by immunohistochemical identification of prostatic acid phosphatase and prostatic specific antigen within the tumor cells.
