By Mayo Clinic staffThe most common signs and symptoms of dermatomyositis include:
- A violet-colored or dusky red rash, most commonly on your face, eyelids, and areas around your nails, knuckles, elbows, knees, chest and back. The rash, which can be patchy with bluish-purple discolorations, is often the first sign of dermatomyositis.
- Progressive muscle weakness, particularly in the muscles closest to the trunk, such as those in your hips, thighs, shoulders, upper arms and neck. The weakness is symmetrical, affecting both the left and right sides of your body, and tends to gradually worsen.
Other dermatomyositis signs and symptoms that may occur include:
- Difficulty swallowing (dysphagia)
- Muscle pain or tenderness
- Fatigue, fever and weight loss
- Hardened deposits of calcium under the skin (calcinosis), especially in children
- Gastrointestinal ulcers and intestinal perforations, also more common in children
- Lung problems
