In a stdudenet course of gross anatomy dissection at Kanagawa Dental College in 2006, we found an extremely rare case of the hepatic artery arising from the superior mesenteric artery of a 78-year-old Japanese male cadaver. This case belonged to type V in Adachi's classification of the celiac trunk and the superior mesenteric artery (1928). The gastro-splenic trunk and hepato-mesenteric trunk both arose from the abdominal aorta and the left gastric artery arose from the gastro-splenic trunk. The hepatic artery arose from the hepato-mesenteric trunk and crossed the portal vein anteriorly.
