Ectopic Liver Tissue Attached to the Gallbladder Wall: a case report

INTRODUCTION: Ectopic liver tissue is a rare entity, reported to occur in several intra-, retro- and extra- peritoneal sites, including the gallbladder. It is usually detected incidentally, during laparoscopy, laparotomy, or autopsy. Several possible mechanisms may explain the development of liver ectopia. Although ectopic liver tissue is usually asymptomatic, it behaves like orthotopic liver, developing the same pathologic conditions. CASE PRESENTATION: We describe the case of a 54-year-old woman who was found to have a nodule attached to the gallbladder wall without any connection with the main liver, during an elective laparoscopic cholecystectomy for gallstone disease. The nodule was removed with the gallbladder and identified histologically as normal ectopic liver tissue. CONCLUSION: It would seem sensible to resect the ectopic tissue if encountered during cholecystectomy for gallstones. Laparoscopic management of ectopic liver can be feasible.
