Dermatomyositis usually occurs from the late 40s to early 60s in adults and from ages five to 15 in children. Females are most affected.
Symptoms include a dusky red rash on the face and eyelids, and in areas around the nails, knuckles, elbows, knees, chest, and back. Muscle weakness is frequent.
Treatment includes medication or other therapies. Surgery may be used to remove calcium deposits.
