Dermatomyositis and Breast Cancer: A Case Report and Review

Breast cancer is the leading cause of death from malignancy in women worldwide, with nearly 500,000 deaths each year. Its diagnosis must be a priority for world health. Breast cancer is the second tumor that can produce a paraneoplastic syndrome after lung cancer. Dermatomyositis with a diagnosis in later ages correlates significantly with an underlying malignancy. Therefore, you should always rule out the presence of a common disease (breast cancer) with the presentation of a rare disease (dermatomyositis).
