Hepatobiliary cystadenoma: a rare hepatic tumor in a child

This report describes a 3-year-old child with a hepatobiliary cystadenoma. Cystadenomas are benign, multilocular, cystic neoplasms that usually occur in middle-aged women. The patients may be asymptomatic, but often there are vague abdominal complaints related to extrinsic compression of the stomach, duodenum, or biliary tree. Recurrence following incomplete excision and the presence of carcinoma within otherwise benign cysts has been documented. Complete resection is the therapy of choice, and thorough histopathologic evaluation is imperative.
