There are numerous reports in the literature suggesting an increased incidence of cancer in the patients with dermatomyositis. Herein we report on a 36-year-old woman with dermatomyositis and malignant teratoma of the retroperitoneum. At first, a diagnosis of SLE was made because she displayed only skin lesions and was free of myopathy. Two years later myopathy and malignant tumor appeared almost concurrently. The final diagnosis was undifferentiated adenocarcinoma (signet ring cell carcinoma) arising from the retroperitoneal teratoma with dermatomyositis. To our knowledge, this is the first reported case of malignant teratoma of the retroperitoneum associated with dermatomyositis.
