Dermatomiositis paraneoplásica en una paciente con cáncer de ovario

We present the case of a 67-year-old woman who developed dermatomyositis preceding diagnosis of ovarian carcinoma. Paraneoplastic syndromes are a group of disturbances associated with malignant neoplasms, but not directly related to invasion by the primary tumor or its metastases. Dermatomyositis is an uncommon paraneoplastic syndrome often associated with different tumors. This entity produces muscular inflammation (polymyositis) and cutaneous manifestations (dermatomyositis). The incidence of cancer in patients with dermatomyositis is estimated to be between 15 and 30%. In patients with dermatomyositis, underlying malignancy should be investigated.
