The accessory liver lobe (ALL) of the gallbladder wall is rare, mentioned by Meckel since 1822. We present two cases of ALL occurring in two adult women. The ALLs were diagnosed at microscopic examination of cholecystectomy specimens for lithiasic cholecystitis and were located at the gallbladder body level. They measured 0.5 and 1.1 cm and were pediculated from the gallbladder serosa. Luschka duct complexes were seen in the adjacent subserosa in one of the cases. The main clinical relevance of ALL of the gallbladder resides in the differential diagnosis with a lymph node and in the risk of peroperative hemorragia or bile leakage by sectioning of the connecting blood vessels and/or bile duct. Intraparietal ALL may interfere with dysmotility, possibly resulting in bile stagnation and stone formation.
