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.
报道了两例前列腺尿道内出现异位前列腺组织或具有前列腺型上皮的腺瘤样息肉的病例。患者为30岁和33岁男性，有肉眼血尿以及排尿时尿道疼痛伴终末肉眼血尿。内镜检查发现前列腺小囊扩张开口处有乳头状病变。活检病理显示为类似前列腺腺体的组织。采用免疫组织化学方法进行的前列腺特异性抗原（PSA）染色呈阳性。文中讨论了该病变的组织发生及其重要性，特别是作为年轻成年男性血尿原因的重要性。
