Orthotopic Liver Transplantation for Primary Intrahepatic Adenosquamous Carcinoma Using A Marginal Graft: the First Case rRport

Abstract Background.Primary intrahepatic adenosquamous carcinoma (iASC) is a very rare subtype of cholangiocarcinoma (CCA), with a worse prognosis than adenocarcinoma. Hepatectomy is still the first choice for iASC, and liver transplantation (LT) for iASC has not been previously reported.Case presentationThe young male patient with an unresectable primary iASC underwent a LT using a marginal fatty liver graft. The overall survival of this patient was 16 months, with a recurrence-free survival of 8 months. The patient had a good quality of life with normal liver function until 3 months before death.Conclusions.This is the first case report of LT as treatment of unresectable iASC using a marginal graft. Although the recipient may benefit from LT, LT for iASC should proceed with caution owing to its more aggressive features.
