Urethral caruncle is one of the benign disorders which occurs frequently after the menopause. We describe a case of urethral caruncle with intestinal heterotopia, in which infiltration by lymphocytes, invagination of the urethral transitional epithelium causing nest formation, lumen formation, hypervascularity as well as teleangiectasia were observed, suggesting the occurrence of metaplasia in the transitional epithelium preceding the intestinal heterotopia. The aetiology and clinical significance of urethral caruncle exhibiting intestinal heterotopia are discussed.
尿道肉阜是绝经后常见的良性疾病之一。我们描述了一例伴有肠化生的尿道肉阜病例，其中观察到淋巴细胞浸润、尿道移行上皮内陷导致巢状形成、管腔形成、血管增生以及毛细血管扩张，提示在肠化生之前移行上皮发生了化生。本文讨论了表现为肠化生的尿道肉阜的病因及临床意义。
