Late onset of severe graft-versus-host disease following liver transplantation

Graft versus host disease (GVHD) is an uncommon but lethal complication following liver transplantation that results from the engraftment of T lymphocytes associated with the liver graft. It usually occurs 2 to 6 weeks after the procedure. We herein report a case of late onset of severe GVHD 4 months after cadaveric liver transplantation for hepatocellular carcinoma in a 54-year-old woman, which was characterized by refractory diarrhea and abdominal pain. Moreover we discuss risk factors of GVHD including the recipient age and cytomegalovirus (CMV) infection.
