Amyopathic dermatomyositis complicated with eosinophilic pneumonia.

ABSTRACT

A 67-year-old woman was admitted to our hospital due to dyspnea on exertion with lung abnormal shadows. A transbronchial lung biopsy specimen demonstrated eosinophilic pneumonia (EP). The patient also exhibited heliotrope eyelids without muscle weakness, which led to a diagnosis of amyopathic dermatomyositis (ADM). As we were unable to find any other causes of EP, we diagnosed her as having EP associated with ADM. Dermatomyositis (DM) has been reported to be associated with various interstitial lung diseases; however, only one case of EP associated with DM has been reported. We herein report the first case of EP complicated with ADM.
