Inflammatory myopathy characterized by a skin eruption that usually precedes muscle weakness with elevated serum levels of muscle enzymes and a skin rash, typically a purplish-red erythema on the face, and edema of the eyelids and periorbital tissue.
The real culprits of dermatomyositis is unknown. Experts think it may be due to a viral infection of the muscles or a problem with the body's immune system. Anyone can develop dermatomyositis, but it most commonly occurs in children age 6 - 16 and adults age 40 - 60. The female are more frequently affected than male.
Research into DM involves factors that may be involved, such as an autoimmune defect, an underlying cancer, genetic predisposition, the potential that the disease may be drug-induced, or that it may be triggered by either a toxic or an infectious agent.
The DM rash looks patchy, dusky, and reddish or purple. It is found on the cheeks, eyelids, nose, elbow, upper chest, back, and knees. Some people also have hardened bumps under the skin (calcinosis). The skin rash and weak muscles are caused by inflammation, or swelling, in the blood vessels under the skin and in the muscles, also called vasculitis. Apart from this people with DM feels general tiredness.
Other common symptoms include.
Shortness of breath.
Differential diagnoses include lupus erythematosus or systemic sclerosis.
