title: Subacute perimyositis.
abstract: We describe a patient who developed a benign myopathy with features suggestive of subacute perimysial inflammation. There was no blood eosinophilia or infectious agent identified. Creatine phosphokinase was not significantly elevated. Electromyography showed a myopathic process. Muscle biopsy showed predominantly subacute perimysial inflammation with rare eosinophils. The patient recovered completely after therapy with glucocorticoids and a nonsteroidal antiinflammatory drug. The features of our case were compared to known causes of myositis with or without eosinophils. It may be part of the spectrum of relapsing eosinophilic perimyositis or may be a condition previously unreported.
