Biliary cystadenoma in the extrahepatic bile ducts is a very rare tumor. A 62-year-old woman with jaundice was admitted to our hospital. Imaging studies revealed a 4-cm cystic lesion around the hepatic hilum, compressing the common bile duct (CBD). When laparotomy was performed, a cystic tumor was detected in the hepatic hilum, filling the lumen of the CBD. Bile duct resection that included the tumor was performed, followed by biliary reconstruction. Microscopically, the cyst wall was lined by a single layer of cuboidal epithelial cells, covering an ovarian-like stroma. The degree of atypia was low and warranted the diagnosis of cystadenoma.
肝外胆管的胆管囊腺瘤是一种非常罕见的肿瘤。一名62岁黄疸女性入住我院。影像学检查显示肝门周围有一个4厘米的囊性病变，压迫胆总管（CBD）。行剖腹手术时，在肝门处发现一个囊性肿瘤，占据了CBD的管腔。进行了包括肿瘤在内的胆管切除术，随后进行了胆道重建。显微镜下，囊肿壁内衬单层立方上皮细胞，覆盖类似卵巢的间质。异型性程度低，符合囊腺瘤的诊断。
