Dystrophic Calcinosis in a Patient with Scleroderma: Imaging Findings and Literature Review

Subcutaneous calcinosis consists of abnormal calcium deposition in soft tissues and is one of the complications of scleroderma, especially in limited systemic sclerosis. It is one of the criteria of CREST syndrome (calcinosis cutis, Raynaud phenomenon, esophageal dysfunction, sclerodactyly, and telangiectasia). A 44-year-old woman with systemic scleroderma for 20 years was presented with pain in the elbow, fingers and toes, and extensive calcinosis in soft tissue. The patient was treated with immunosuppressive medications due to lung parenchymal involvement and received various drug and surgical treatments for soft tissue calcinosis. In situations of poor response to medication, surgical treatment could be the only option for treating symptomatic lesions.
