Abstract
Inflammatory myopathies have an increased risk of malignancy, the one with the highest association being dermatomyositis. The neoplasm can be solid or hematologic. There are clinical and laboratory factors that can increase or decrease the risk for the presentation of a myositis as a paraneoplastic disease. Among the main risk factors, the presence of anti-TIF1, anti-NXP2 and to a lesser extent anti-SAE antibodies have been observed. The main theory of its origin points to the immune response derived from the creation of mutated proteins by cancer cells. The diagnosis of malignancy can be made before, during or after the diagnosis of dermatomyositis. There is no established therapeutic regimen, however the use of steroids, immunosuppressants or immunoglobulins have been proposed, as well as effective cancer therapy.
