Infectious mononucleosis hepatitis: report of two patients.

Icteric hepatitis and fulminant hepatic failure (FHF) are rare in infectious mononucleosis (IM). We report two patients with icteric IM hepatitis; one died after developing FHF, the other recovered uneventfully. Epstein-Barr virus infection causing hepatitis and FHF should be suspected when tests for other hepatotrophic viral infections are negative.
