Though dermatomyositis is a well-known paraneoplastic syndrome, its particular relationship with breast cancer is yet to be thoroughly defined and there are no established guidelines for the treatment. The occurrence of dermatomyositis seems to be associated with more advanced stages of breast cancer, particularly with invasive ductal carcinoma. Our case elaborates a primary presentation of breast cancer as dermatomyositis, its musculoskeletal manifestation and management. Treating the cancer alone does not sufficiently address the symptoms of dermatomyositis, which can greatly impact quality of life. Thus, employing a multidisciplinary strategy with strong collaboration of rheumatologists is crucial for the diagnosis and treatment.
