Dermatomyositis is rare inflammatory condition of the skin and muscles that the incidence is 5 cases per million population per year. This disease was strongly associated with malignant disease, particularly ovarian, lung, pancreatic, stomach and colorectal cancers, and non-Hodgkins lymphoma. A 56-year-old female patient had a ovarian tumor, thereafter she presented with typical skin lesions and muscle weakness. And then we found she had a colon cancer. Here we present the case with brief review of literature.
