Acute Necrotizing Eosinophilic Myocarditis in a 27-year-old Woman: A Case Report.

Acute necrotizing eosinophilic myocarditis is an uncommon type of myocarditis commonly presenting as fulminant congestive heart failure and histologically characterized by dense eosinophilic infiltrates in a background of necrotic cardiomyocytes. We present the case of a 27-year-old woman who died suddenly due to severe shock and multiorgan failure and was found to have acute necrotizing eosinophilic myocarditis at autopsy. We discuss the possible precipitating factors underlying our case and the considerations this case and others in the literature provide to pathologists investigating the unexpected death of young adults.
