Dermatomyositis is one of a group of acquired muscle diseases called inflammatory myopathies (disorder of muscle tissue or muscles), which are characterized by chronic muscle inflammation accompanied by muscle weakness. The cardinal symptom is a skin rash that precedes or accompanies progressive muscle weakness.[1] Dermatomyositis may occur at any age, but is most common in adults in their late 40s to early 60s, or children between 5 and 15 years of age.[2] There is no cure for dermatomyositis, but the symptoms can be treated. Options include medication, physical therapy, exercise, heat therapy (including microwave and ultrasound), orthotics and assistive devices, and rest.[1] The cause of dermatomyositis is unknown.[3]
