Two cases of urethral polyp with prostatic-type epithelium were reported. One was a 36-year-old male and the other was a 69-year-old male. They were presented with hematuria and hematospermia, respectively. Polyps were recognized at the prostatic urethra in the vincinity of the vermontanum in both patients. These lesions were treated with TUR.
One (36-year-old) developed recurrence 4 years after the initial TUR. These polyps in both patients were found to be covered by columner cells which were stained positively by PSA (prostate specific antigen) and PAP (prostatic acid phosphatase) using immunohistochemical methods. This suggested that the epithelium of these lesions were of prostatic type. In some areas of the recurrent specimen from the 36-year-old case, the head of this polyp was lined by transitional cell epithelium and the foot by the prostatic-type epithelium. These observations were discussed with special emphasis on the nature and histogenesis of this lesions.
