A 44-year-old woman with dermatomyositis had multiple painful calcinosis cutis lesions that were affecting her daily living. Many tests and labs were run to assess the severity and the progression of these lesions. Multiple treatment options were tried and failed before, leading to an introduction of topical sodium thiosulfate. The topical formula provided a great decrease in pain and discomfort for the patient. This led to the patient never needing injectable treatment that would have caused more pain both physically and emotionally
