Popis: ABSTRACT We report two cases of hemochromatosis-like disease in captive Brazilian tapirs, Tapirus terrestris in Pará state, Brazil. Both animals presented symptoms of chronic hepatopathy associated with marked accumulation of hemosiderin. The coloration of Perls demonstrated pronounced iron accumulation in macrophages in the portal space, Kupffer cells, and, to a lesser extent, in the hepatocytes of the periportal region. Marked portal fibrosis was evidenced by Masson’s trichrome. The pathological mechanisms of this disease in tapirs are not yet well established. It has been suggested that the species may have different mechanisms of iron absorption and elimination, rendering them sensitive to elevation in dietary levels of this metal. Two previous reports of this disease in T. terrestris exist from zoos in Australia and Scotland. This is the first report of this disease in tapirs in Brazil based on histopathological and histochemical findings.
