Inflammatory myopathy is characterized by symmetrical proximal muscle weakness, elevated muscle enzyme levels and favorable response to glucocorticoids therapy. Although periorbital edema is a common manifestation of inflammatory myopathy, generalized subcutaneous edema is very rare. We report here a case of a 47-year-old female patient with acute polymyositis/systemic lupus eryth-ematosus overlap syndrome with generalized subcutaneous edema and interstitial lung disease. We aggressively treat-ed the disease with high-dose glucocorticoids, intravenous immunoglobulin, and immunosuppressive agents.
