Abstract

Idiopathic eosinophilic polymyositis has been described in human beings and dogs, but has not been previously diagnosed in a rodent. A Swiss-derived mouse was submitted for necropsy because of weakness, anorexia, and difficulty righting itself when rolled onto its back. No gross lesions were apparent. Microscopically, there were accumulations of eosinophils in skeletal muscle and heart. Focal, myofiber necrosis and degeneration were associated with the cellular infiltrates in these tissues. No parasites were found associated with these lesions. The disease in this mouse may have had a genetic or common-exposure component.
