title: Multicystic biliary hamartoma of the liver.
abstract: Multicystic biliary hamartoma (MCBH) is a very rare hamartomatous cystic nodule of the liver, which has recently been described as a new entity of a hepatic nodular lesion. We report a unique case of MCBH with a review of the literatures. A hepatic multicystic mass of segment 3 was detected in a 52-year-old male by abdominal computed tomography, and resection of this lesion was performed. Macroscopic examination revealed a 2.7×2.0 cm nodular mass with a multicystic honeycomb cut surface. Histologically, this lesion consisted of multiple dilated cystic ducts lined by biliary type epithelial cells, periductal glands and connective tissue, which included small amounts of hepatic parenchyma and blood vessels. Recognition of this unusual lesion is essential to avoid confusion with other cystic tumors of the liver, and to learn more about its natural history and response to treatment.
