Ectopic liver tissue on gallbladder (choristoma): Two case reports

Ectopic liver tissue is a rare developmental anomaly and is most commonly seen on the gallbladder. A 45-year-old male and 41-year-old female patient underwent laparoscopic cholecystectomy due to gallstones, and ectopic liver tissue was found on the patients’ gallbladder. During the operation, ectopic liver tissue removed with the surgical specimen material. Pathology report is compatible with the usual liver parenchyma. Discussion: Although there is no strong information about the long-term follow-up results of the ectopic liver, surgical resection is recommended due to the high probability of carcinogenesis (hepatocellular carcinoma). However, this possibility is lower in localizations on the gallbladder. Therefore, if there is a pathology in the gallbladder, its excision with the gallbladder is recommended
