Dermatomyositis (DM)DM is an autoimmune condition that causes skin changes and muscle weakness. Symptoms can include a red skin rash around the eyelids, red bumps around the joints, and severe muscle weakness in the arms and legs. A skin rash often precedes the muscle weakness. The muscle weakness gets worse over time and can lead to rigid joints, pain, and muscle wasting. Other organs may be affected as well, including the lungs and digestive tract. DM is most common in adults between ages 40 and 60 or in children between ages 5 and 15.1,2Materials
