INTRODUCTIONMulticystic biliary hamartoma is a rare liver tumor that was first described in 2005. Only nine cases are reported in the literature and all of them originate from Eastern patient populations, specifically Japan and Korea.PRESENTATION OF CASEHerein we report the occurrence of the tenth multicystic biliary hamartoma reported to date, arising in a Caucasian American woman initially presenting with abdominal pain. At 4.7 cm this is the second largest tumor reported to date and the only one arising in a Western patient population.DISCUSSIONThe patient underwent multimodality imaging and the tumor was biopsied preoperatively, but the diagnosis remained unclear. An extended right hepatectomy was performed for resection of her tumor, and the tumor was definitively diagnosed based on the surgically resected specimen. As all nine of the previously reported cases also underwent resection, the natural history of this lesion remains unknown. The lack of both recurrence and tumor spread in the previously reported cases indicates that this may be a benign lesion not requiring surgical resection unless symptomatic.CONCLUSIONMulticystic biliary hamartoma is an extremely rare tumor. Increased awareness of the radiologic and pathologic features will likely lead to the diagnoses of further cases in both Western and Eastern populations and could potentially assist with preoperative diagnosis. The natural history and optimal management of this tumor remain uncertain.
