Abstract
- Biliary hamartoma is a benign neoplasm that normally measures < 1 cm in diameter and can occur throughout the liver. It is composed of dilated bile ducts embedded in a fibrous stroma and is a congenital fibrocystic disease derived from incomplete remodeling of the ductal plates in the embryonic development of intrahepatic bile ducts. Incidentally found in imaging studies without clinical symptoms, it is known to be infrequently accompanied by cholangiocarcinoma. However, biliary hamartoma must be differentiated from other cystic lesions that are similar to metastatic tumors or abscesses. We describe four cases of biliary hamartoma.
