Abstract: 【Abstract】 Dermatomyositis, a common autoimmune disease in clinical practice, often involves muscles and lungs, and can be complicated by malignant tumors, and the lung involvement can be fatal. Therefore, early diagnosis and treatment of dermatomyositis is of great benefit for the reduction of muscle and lung injury, early recognition and management of malignant tumors, and improvement of prognosis and survival rate of patients. However, the heterogeneity and various clinical manifestations of dermatomyositis pose challenges to early diagnosis. This article describes risk factors for dermatomyositis complicated by rapidly progressive pulmonary interstitial fibrosis, dysphagia or malignant tumors, and proposes a mode of "rashes + nailfold capillary abnormalities + myositis antibodies" for the early diagnosis of dermatomyositis, early recognition of important visceral injury and tumors, and early management, in order to improve overall survival rate of patients.

Key words: Dermatomyositis, Lung diseases, interstitial, Neoplasms, Myositis antibodies, Early diagnosis
