A RETROSPECTIVE STUDY OF HEPATIC HEMOSIDEROSIS AND IRON STORAGE DISEASE IN SEVERAL CAPTIVE AND FREE-RANGING AVIAN SPECIES.

Some wild species of mammals and birds are prone to excessive iron accumulation, especially when maintained in human care. Hemosiderosis is the process of intracellular accumulation of iron without evidence of toxicity, whereas hemochromatosis is characterized by severe iron accumulation with accompanying organ damage. Iron storage disease (ISD) occurs when organ damage is severe and causing clinical signs.

Hepatocellular carcinoma in two captive golden-headed lion tamarins (Leontopithecus chrysomelas).

Two cases of hepatocellular carcinoma (HCC) in 2 female captive golden-headed lion tamarins (Leontopithecus chrysomelas) are described. HCC was diagnosed in both, with pulmonary metastasis in one of them. Neoplastic cells were positive for hepatocyte-specific antigen (HSA) by immunohistochemistry, confirming the diagnosis.
