Calcium Deposits

Calcium deposit is a condition where irregular quantities of calcium phosphate are displaced in the soft tissue of the affected individual's body. The displaced calcium hardens in these tissues, forming nodules that may be painful, cause skin ulcers, and impede normal function. Calcium deposits in an affected individual tend to be the most problematic when they develop in the joints, such as the wrists and feet. The exact mechanism that causes the development of deposits of calcium in dermatomyositis patients is not fully understood. However, these deposits may be associated with changes to the individual's blood vessels and inflammatory damage in the tissues from dermatomyositis. Calcium deposits are more likely in children affected by dermatomyositis than they are in adults with the condition. In individuals who have calcium deposits as a complication of their dermatomyositis, the deposits usually develop within the first three years that follow their diagnosis.
