Orthotopic liver transplantation in patients with acute toxic hepatitis has not, to our knowledge, been reported. Our recent experience with orthotopic liver transplantation in a 3-year-old girl with acute hepatic failure secondary to Amanita poisoning is described. Aspects of Amanita toxin-induced pathophysiology pertinent to orthotopic liver transplantation are discussed. The results in this case provide important implications for patients with fulminant hepatic failure secondary to other hepatotoxic agents in whom liver transplantation is considered.
