ABSTRACT

Esta análise morfológica e imuno-histoquímica de hepatopatias fulminantes da Amazônia incluindo a série histórica original de Hepatite de Lábrea (HL) e casos de Febre Amarela (FA) concentrou-se em padrões de lesão . Mostraram-se características da FA: morte celular por apoptose medio-zonal, balonização hepatocelular, elevado índice de proliferação celular avaliado pelo PCNA e flebite portal. Os casos de HL mostraram extensa necrose hepatocelular lítica, células “em mórula”, regeneração hepatocelular com multinucleações e transformação pseudo-acinar, flebite portal e centro-lobular, com extinção parenquimatosa, depósitos portais de fibras elásticas e colágeno tipo I e depósitos lobulares de colágeno III / This morphologic and immunohistochemical analysis of fulminant hepatic failure from Amazon Basin, including the original historical series of Labrea Hepatitis (LH) and of Yellow fever (YF) cases was concentrated on lesion patterns. Midzonal apoptotic cellular death, hepatocellular ballooning degeneration, high cellular proliferation index assessed by PCNA and portal phlebitis were shown to be characteristics of YF. LH cases showed extensive lytic hepatocellular necrosis, “morula cells”, hepatocellular regeneration with multinucleation and pseudo-acinar transformation, portal and hepatic vein phlebitis, with parenchymal extinction, portal elastic fibers and type I collagen fibers and lobular type III collagen fiber deposition...
