A 38-year-old man was referred to our hospital because of elevation of serum alkaline phosphatase(ALP) level. Abdominal computed tomography(CT) demonstrated a large mass lesion with probable connection to the left lobe of the liver at the left subphrenic area. Extrahepatic hemangioma was suspected and laparoscopic procedure was performed. Laparoscopic observation demonstrated the tumor, connected to the liver by a mesenterium containing some vessels, the tumor was resected using an automatic suture device. Histological examination revealed that the tumor consisted of almost normal hepatic tissue and thus we diagnosed it as an accessory lobe of the liver(ALL). His postoperative course was uneventful. ALL is an extremely rare hepatic malformation. Resection is recommended if the ALL is pedunculated, because torsion of ALL can be the cause of acute abdominal pain. If there is an unknown tumor around the liver, ALL should be suspected. For this condition, laparoscopic procedure is very useful.
