RESUMO
Polyarteritis nodosa is an idiopathic necrotizing vasculitis that affects small to medium-sized arteries. We describe a case of polyarteritis nodosa in a captive common wooly monkey (Lagothrix lagotricha) associated with transmural intestinal necrosis and secondary peritonitis. This condition must be considered for differential diagnosis of segmental arteritis in neotropical primates.

Cardiac disease is of importance in captive chimpanzee (Pan troglodytes) health. Here we report an eosinophilic and necrotizing myocarditis in a 17-y-old chimpanzee with no previous history of cardiac disease that progressed to death within 48 h. Toxic and infectious causes were ruled out. The chimpanzee had eosinophilia at different occasions in previous years. The animal had a severe, diffuse, and acute monophasic necrotizing myocarditis, with a moderate lymphoplasmacytic infiltrate that was rich in eosinophils. Ante- and postmortem investigations are compatible with an unusual eosinophilic myocarditis with clinical evolution and morphology comparable with human eosinophilic myocarditis secondary to hypereosinophilic syndrome.
