title: Labrea-like hepatitis in Vitoria, Espirito Santo State, Brazil: report of a case.
abstract: A case of fulminant hepatitis with microvesicular steatosis resembling Labrea's fever, diagnosed in Vitoria (ES) is reported. The 16 year old boy presented with severe epistaxis, agitation, jaundice and hemorrhagic vomiting and died two days after admission to the emergency unit of the University Hospital. The disease started five days before with fever, myalgias, dark urine and jaundice and progressed with psychic agitation, torpor and coma. The liver and spleen were not palpable. HBsAg was negative in the serum. The autopsy showed acute hepatitis with lytic necrosis confluent in the midzonal and periportal areas with massive microvesicular steatosis in the remaining hepatocytes. Mononuclear cells predominated in the exudate. The reticulum showed condensation in the necrotic areas without typical bands of collapse. The portal tracts were edematous with mononuclear infiltration and mild bile duct proliferation. Absence of cholestasis. Except for the confluent midzonal and periportal necrosis this case showed several clinical and morphological aspects of the Labrea fever described from the East Amazon, demonstrating that the anatomical picture of this disease probably is not in related to a factor peculiar to the Amazon region.
