Liver transplantation for treatment of giant hepatocellular adenomas. Liver transplantation and surgery Mueller, J., Keeffe, E. B., Esquivel, C. O. 1995; 1 (2): 99-102


Giant hepatocellular adenomas are associated with a high incidence of rupture with intra-abdominal hemorrhage and may also undergo malignant transformation. If resection is not technically feasible, liver transplantation should be a treatment option. The aim of this report is to describe the indications, feasibility, and outcome of liver transplantation for hepatocellular adenomas. A 66-year-old man with a 17-cm hepatocellular adenoma originating in the left lobe but involving nearly the entire liver and a 35-year-old woman with a 20-cm tumor involving the right lobe of the liver and compressing the left lobe underwent liver transplantation without complication. In both cases, a histological diagnosis was made by core needle biopsy preoperatively, and resection was technically not possible. Hepatocellular adenoma involving nearly all of the liver with no evidence of malignant change was confirmed in the explant liver from both cases. Giant hepatocellular adenomas may be unresectable and require liver transplantation for complete removal to prevent potential rupture with hemorrhage or malignant transformation.
