Dermatomyositis Definition
Definition
Dermatomyositis is a noninfectious inflammation of muscle tissue and skin.
Dermatomyositis and its sister disease, polymyositis, belong to a large group of connective tissue disorders that includes lupus erythematosus, rheumatoid arthritis, and scleroderma (systemic sclerosis).
They are all believed to be “autoimmune disorders,” where the body launches an attack against its own tissue. These chronic, progressive conditions lead to tissue damage. They can be serious conditions that require care from your doctor. The sooner these disorders are treated, the better the outcome. If you suspect you have this condition, contact your doctor right away.
