Clinical case of subcutaneous calcification in a patient with dermatomyositis

The article presents a clinical case of a patient with subcutaneous calcification. Deposits of calcium salts in the skin and subcutaneous fat can be a manifestation of a number of diseases. The article describes the characteristics of the clinical course of the disease and the laboratory and instrumental diagnostic methods. Judging by the dynamics of changes in the skin and subcutaneous fat, the presence of an immuno-inflammatory disease in the anamnesis, slow progression against the background of immunosuppressive therapy, the diagnosis was made: low activity dermatomyositis (as an outcome of juvenile dermatomyositis) with lesions of skin and muscles in the anamnesis. It should be noted that subcutaneous calcification is more characteristic for juvenile dermatomyositis.
