During the laparoscopy, an accessory liver lobe, 15 mm in size, was noted on the serosal surface of the gallbladder body with a connection to the main liver sections (Fig. 4).
(a) Postoperative macroscopic findings of the resected specimen showed an accessory liver lobe on the gallbladder (arrow). (b) Microscopic findings of the resected specimen showed normal hepatic tissue with a bile duct (arrow). (H.E. x 40).
