title: [A case of benign polyp with prostatic-type epithelium in the bulbar urethra].
abstract: We report a case of benign polyp with prostatic-type epithelium in the bulbar urethra. A 77-year-old man was admitted to our hospital with voiding disturbance. Cystourethroscopy revealed a papillary tumor with a stalk in the 10 o'clock direction of the bulbar urethra. Transurethral resection of the urethral tumor was performed. Histopathological examination of the polypoid lesions showed papillary proliferative tissue. Immunohistochemical staining of prostate specific antigen was positive. The urethral tumor was diagnosed as benign polyp with prostatic-type epithelium.
