Abstract

Dermatomyositis is a disorder of unknown etiology characterized by an inflammatory myopathy involving striated skeletal muscle and associated characteristic skin lesions.The relationship between dermatomyositis and malignant tumor remains controversial,but we must be concerned about evaluation of suspected malignancy in a patient with dermatomyositis. We present a case of dermatomyositis associated with lung cancer.A 51-year-old male has suffered proximal muscle weakness and facial erythema for 2 months.Pathologic results showed adenocarcinoma and pneumonectomy of the left lung was performed.Myositis resolved completely after removing the malignant mass.Few cases of malignant tumors associated with dermatomyositis were reported in Korea,but dermatomyositis associated with non-small cell lung cancer and complete remission of myositis after the tumor resection has not been reported previously.
