Eosinophilic Granulomatous Myocarditis in Two Pigs

? 2022 Elsevier LtdEosinophilic myocarditis is a human condition that has been rarely documented in animals. We now report two unrelated porcine cases of idiopathic eosinophilic granulomatous myocarditis that resembled the human disease and which were associated with sudden death. The most relevant gross finding in both cases was marked cardiomegaly, accompanied by raised, multifocal to coalescent small white nodules (1–2 mm) and poorly demarcated multifocal pale areas in the epicardium. Histologically, there were multifocal to coalescent areas of cardiomyocyte loss with replacement by an intense inflammatory infiltrate of eosinophils and epithelioid macrophages, and proliferation of fibrous connective tissue. Immunohistochemistry for porcine circovirus type 2 (PCV2) and Toxoplasma gondii, in-situ hybridization and quantitative polymerase chain reaction tests for PCV2 and porcine circovirus type 3 and aerobic bacterial culture on myocardium samples were negative.
