title: [A case of mucinous cystic neoplasm of the liver].
abstract: We present a case of resected mucinous cystic neoplasm of the liver in a 71-year-old woman admitted to our hospital with epigastric discomfort. Abdominal ultrasonography and computed tomography revealed a multi-locular cystic tumor measuring 35 mm in diameter in segment IV of the liver. Left hepatic lobectomy was performed based on the diagnosis of mucinous cystic neoplasm of the liver; subsequent histology revealed that the tumor was multi-locular, cystic, and lined with a single layer of columnar epithelium with low-grade atypia and was associated with a typical ovarian-like stroma. There was no evidence (imaging or histological) to support communication of the cyst with the intrahepatic bile duct, despite modest bile deposition being observed in the cystic wall. The definitive diagnosis was mucinous cystic neoplasm with low-grade intrahepatic epithelial neoplasia.
