[A case of infectious mononucleosis complicated with severe jaundice].
A 28-year-old male was admitted to our hospital with tonsillitis and jaundice. Laboratory findings showed leukocytosis (rate of atypical lymphocytes was 40%), liver dysfunction and hyperbilirubinemia. Epstein-Barr virus (EBV) viral capsid antigen (VCA) IgM and IgG antibodies were positive, and EB nuclear antigen (EBNA) antibody was negative. Abdominal ultrasonography demonstrated hepato-splenomegaly and swelling of intraperitoneal lymph nodes. A diagnosis of infectious mononucleosis was made due to EBV infection. Conservative therapy was given. Total bilirubin and alkaline phosphatase increased to maximum levels of 10.2 mg/dl and 1,590U/l. A liver biopsy specimen revealed infiltration of lymphocytes in sinusoids and portal areas, focal necrosis and intrahepatic cholestasis in parenchyma. Liver function tests returned to normal limits and EBV VCA IgM antibody became negative within 10 weeks from onset.
