Ten cases of prostatic epithelial polyps of the prostatic urethra are reported. The ages of the patients were from 27 to 69 years, with a mean of 44 years. The most common clinical signs were gross hematuria, microhematuria, hematospermia, and dysuria. All specimens, obtained by transurethral resection, had a papillary or polypoid configuration. The tissue had a glandular structure that resembled that of the prostate. Prostate-specific antigen and prostatic acid phosphatase were found in the epithelial cells of the polyps by indirect immunoperoxidase staining. The polyps seemed to be hyperplasia of prostate-specific antigen and prostatic acid phosphatase-positive epithelial cells of the prostatic gland or duct, especially that of the latter.
