 Dermatomyositis often complicates malignant tumor and it is reported to occur in 30~40% of cases of malignant tumor. Most cases of dermatomyositis with malignant tumor initially reveal the symptoms of dermatomyositis, but both diseases are finally diagnosed within 6 months. In Japan, 40 % of malignant tumors are gastric carcinomas diagnosed when they are in Stage III-IV of TNM classification, but are rarely diagnosed in their early stage. Gastric cancer is usually located at the upper part of the gastric body and has no relation to the histological type. It is highly suspected that malignant tumor plays some part in the etiology of dermatomyositis because there are so many reports of improvement of dermatomyositis after tumor therapy for example gastrectomy. Because of this relationship, observation of the gastrointestinal tract is necessary when dermatomyositis is found.
