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.
