Dermatomyositis (DM) is an idiopathic inflammatory disease that affects the skin, striated muscles, and other organs. About 20% of the cases correspond to Clinically Amyopathic Dermatomyositis (CADM), a subgroup of DM. This consists of characteristic skin findings of DM, but without myopathic associate1. In both situations, 20% to 30% are associated with malignancy, especially with
ovarian, breast and lung cancer. This case report aims to emphasize the importance of being familiar with the clinical presentation of the disease and the significant association with malignancies, once early diagnosis reduces patient mortality.
