Mucinous cystic neoplasms (MCNs) are uncommon cystic lesions that arise in the liver and biliary system (MCN-LBS) and the pancreas (MCN-P) and rarely arise from the extrahepatic biliary system. Histologically, these lesions are defined by the presence of variably mucin-producing epithelium with ovarian-like, hypercellular mesenchymal stroma. Herein, we present a case of extrahepatic MCN-LBS in a 51-year-old woman. This lesion arose from the cystic duct and was removed via laparoscopic cholecystectomy. Histologic examination confirmed the diagnosis. To our knowledge, this is the third case report of an MCN-LBS arising from the cystic duct in the English literature. In this article, we review clinical and histologic characteristics of MCNs and present two other reports of MCN-LBS of the cystic duct.
黏液性囊性肿瘤（MCNs）是一种罕见的囊性病变，可发生于肝脏和胆道系统（MCN-LBS）以及胰腺（MCN-P），极少起源于肝外胆道系统。从组织学上看，这些病变的特征是存在产生不同量黏液的上皮细胞以及类似卵巢的、细胞丰富的间充质基质。在此，我们报告一例51岁女性的肝外MCN-LBS病例。该病变起源于胆囊管，通过腹腔镜胆囊切除术切除。组织学检查确诊了该诊断。据我们所知，这是英文文献中第三例关于起源于胆囊管的MCN-LBS的病例报告。在本文中，我们回顾了MCNs的临床和组织学特征，并呈现了另外两例胆囊管MCN-LBS的报告。
