Cloacogenic carcinoma is a rare form of neoplasia (4-14% of tumours of the colon-rectum) which occurs on the transitional epithelium of anal canal. An extra-visceral location is rare. The paper reports a case of cloacogenic carcinoma sited on the perianal skin, treated with radiotherapy and local surgical excision. It is important to perform a biopsy and a thorough endoscopic examination of all ano-perianal lesions in order to separate those of dermatological relevance from those of surgical relevance, and at the same time to determine the exact histological type of the latter group so as to select the correct therapeutical approach.
泄殖腔源癌是一种罕见的肿瘤类型（占结直肠癌肿瘤的4%-14%），发生于肛管的移行上皮。发生于脏外部位的情况罕见。本文报道了1例位于肛周皮肤的泄殖腔源癌病例，采用放疗和局部手术切除进行治疗。对所有肛门-肛周病变进行活检和全面的内镜检查很重要，以便将皮肤相关病变与手术相关病变区分开来，同时确定后一组病变的确切组织学类型，从而选择正确的治疗方法。
