title: [Two cases of ectopic prostatic tissue in the prostatic urethra].
abstract: Two cases of ectopic prostatic tissue or adenomatous polyps with prostatic type epithelium in the prostatic urethra were reported. They were 30-and 33-year-old males suffering from gross-hematuria and from urethral pain on urination with terminal gross-hematuria. Endoscopic examination revealed papillary lesions from the dilated orifice of the prostatic utricle. Biopsied pathology demonstrated a tissue similar to that of the prostatic gland. PSA (prostatic specific antigen) stain using immunohistochemical methods was positive. Histogenesis and the importance of this lesion particularly as a cause of hematuria in the young male adult were discussed.
