We report a case of liver hemangioma with extrahepatic growth in a 53-year-old man,who was admitted　to our hospital after he was suspected to have a liver tumor during a routine medical check-up.An abdominal　computed tomography(CT)scan revealed a partially enhanced mass,11 cm in diameter.Abdominal angiography　revealed a tumor that had a cotton wool-like stain,which was fed by the left lateral hepatic artery(A2).　After the patient was diagnosed with liver hemangioma showing extrahepatic growth,we performed a handassisted　laparoscopic partial hepatectomy.The resected specimen was 11×10×8 cm in diameter and 424g in　weight. A histopathological analysis revealed that the tumor was a cavernous hemangioma.　Hand-assisted laparoscopic surgery permits an adequate surgical field, and other essential management procedures during surgery.Laparoscopic hepatectomy using hand-assisted laparoscopic surgery is thus one of　several effective procedures that provide a superior level of operability and safety
