10 Dermatomyositis Symptoms
Reviewed: Dr. Gromatzky
Symptom #10: Calcinosis
Calcinosis is the formation of calcium deposits in the soft tissues of the body. Types of calcinosis include dystrophic calcification, metastatic calcification, and tumoral calcinosis. It is a distressing late complication, although it can also appear early in juvenile dermatomyositis. It is seen in 30 to 70 percent of juvenile dermatomyositis cases and is less common in adults.
It contributes to joint contractures and muscle atrophy. Calcium deposits in the skin may lead to sterile necrotic abscess and cutaneous ulceration. The severity of the calcinosis typically correlates with the level of long-term disability.
