Dermatomyositis
Definition
Dermatomyositis is a muscle disease characterized by inflammation and a skin rash. It is a type of inflammatory myopathy.
Overview, Causes, & Risk Factors
The cause 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 5 - 15 and adults age 40 - 60. Women develop this condition more often than men do.
Polymyositis is a similar condition, but the symptoms occur without a skin rash.
