Acute hepatic failure caused by primary Epstein-Barr virus (EBV) infection has been reported in the literature in 16 cases, with an overall mortality of 87%. We report a case of fulminant hepatic failure in an immunocompetent young girl caused by primary EBV infection that was treated by orthotopic liver transplantation. After transplantation she has been treated with low-dose immunosuppression, a pooled gammaglobulin preparation containing anti-EBV antibodies, and anti-viral therapy. The patient is presently doing well 2 years after transplantation without evidence of clinical EBV infection, primary immunodeficiency, or lymphoproliferative disease.
