Two Cases of Calcinosis Cutis Combined with Rheumatologic Disease

The calcinosis, dystrophic soft tissue calcification, occurs in damaged or devitalized tissues normal calcium/phosphorus metabolism. It is the subcutaneous tissues of connective tissues disease - primarily systemic lupus erythematosus, scleroderma, or dermatomyositis - and may involve a relatively localized area. The calcinotic accumulations may result in muscle atrophy, joint contractures, and skin ulceration complicated by recurrent episodes of local inflammation and infection. Calcinosis may be the source of both pain and disability in connective tissue disease patients. While various therapeutic modality have been used, no treatment has convincingly prevented or reduced calcinosis. We report two cases of calcinosis cutis combined with rheumatic disease.
