Calcium Deposits in Children

A calcium deposit is a hardened mass of calcium that develops under your skin or in an area of muscle or fat. Children who are born with genetic disorders, such as Down syndrome, muscle inflammation or soft tissue abnormalities may be more likely to develop calcium deposits.

Physical Characteristics

• Children who have calcium deposits may appear to have small rocks or pebbles under their skin. The deposits can become as large as a grapefruit in some cases, according to The Myositis Association.

Significance

• Calcium deposits that are very large may cause pain and limited movement. Small areas of calcinosis may not hurt, but still feel hard.

Causes

• One of the main causes of calcium deposits in kids is a condition called juvenile dermatomyositis. Juvenile dermatomyositis (JDM) is a rheumatic disease that is characterized by a skin rash and muscle pain and weakness. The Institute for Integrative Healthcare Studies notes that children who have blood drawn from their heels frequently, may also be at risk for calcium deposits.

Treatment

• The Myositis Association reports that cases of pediatric calcinosis are not always easy to treat. Controlling underlying medical conditions may reduce the occurrence of the deposits. Physical therapy can help children who have a limited range of motion due to the calcium formations.

Complications

• Some children may have calcium deposits that work their way up to the surface of the skin and break open. The Cincinnati Children's Hospital Medical Center states that drainage can cause infection in some people.
