title: Papillary adenoma of the prostatic urethra.
abstract: Six patients with papillary adenoma of the prostatic urethra are described. Their ages ranged from 39 to 70 years old. Two of them showed evidence of clinical recurrence 1 year after treatment. The pathological features as well as the immunohistochemical demonstration of prostate specific antigen (PSA) and prostatic acid phosphatase (PAP) are illustrated. A brief review of the literature is discussed with special emphasis on the histogenesis and nature of this lesion.
