Abstract
Case 1 : A 52-year-old man presented with right hypochondriac pain. He was diagnosed with cholecystitis, and treated with antibiotics. After pain resolved, laparoscopic cholecystectomy was performed. During the operation, a reddish-brown nodule was found attached to the gallbladder. Pathologically, the nodule represented liver tissue and was identified as an accessory liver.
Case 2 : A 74-year-old woman visited the local doctor with epigastralgia. She was diagnosed with cholecystitis and choledocholithiasis, and treated with removal of the stone by ERCP and antibiotics. Pain resolved and she was referred to us for laparoscopic cholecystectomy. During the operation, a reddish-brown nodule was found attached to the gallbladder. Pathologically, the nodule represented liver tissue and was identified as an accessory liver.
Accessory liver is a rare variation that has been described in about 100 cases. Generally, this finding has been identified during operations for other diseases, as in our cases. We encountered these 2 cases, and report with some additional considerations.
