Patients with breast cancer normally present with breastlump or abnormal mammogram. Dermatomyositis is rarelythe first presentation. We present a case of a 63-year-oldwoman who had generalised dermatitis, progressive fatigueand muscle weakness. She was first diagnosed asdermatomyositis and subsequently breast cancer. Her rashand muscle weakness progressed drastically over a month.Tumescent mastectomy and axillary surgery was performed,which led to gradual regression of her dermatomyositis oversix months.
