Primary retroperitoneal mucinous cystadenocarcinoma (PRMC) is a rare tumour, similar to its ovarian counterpart but without any evidence of ovarian, pancreatic or another extra-retroperitoneal origin. Histogenesis of this neoplasm remains uncertain. Mucinous or coelomic metaplasia of retroperitoneal mesothelium has been recently proposed as its origin. In a 43-year-old woman with a 15-cm cystic lesion in the right retroperitoneum mucinous cystadenocarcinoma was diagnosed, and no primary tumour was identified. Two peritoneal endometriotic foci were found on further surgery. We suggest a common histogenesis for PRMC and these endometriotic foci.
原发性腹膜后黏液性囊腺癌（PRMC）是一种罕见肿瘤，与其卵巢对应肿瘤相似，但无任何卵巢、胰腺或其他腹膜外起源的证据。该肿瘤的组织发生仍不确定。最近有人提出腹膜后间皮的黏液性或体腔化生是其起源。一名43岁女性，右侧腹膜后有一个15厘米的囊性病变，诊断为黏液性囊腺癌，未发现原发性肿瘤。进一步手术时发现两个腹膜子宫内膜异位病灶。我们认为PRMC和这些子宫内膜异位病灶有共同的组织发生。
