title: [Atypical hepatitis].
abstract: Acute viral hepatitis has a rather homogeneous clinical pattern, excepting a few features which are related to the specific viral agent. However, a few cases may be defined "atypical", as fas as clinical features, transmission pattern, serology are concerned. These include cholestatic hepatitis syndrome, fulminant HEV hepatitis during pregnancy, neonatal hepatitis. Non-typical aspects may be observed when extrahepatic manifestations are present (cryoglobulinemia, bone marrow aplasia, guillain-Barré syndrome, peripheral neuropathy, skin involvement, etc.). Finally, viral hepatitis may be "atypical" when associated with other infections (malaria, typhoid fever, etc.), mostly in patients from tropical Countries.
