What is the long term prognosis of dermatomyositis?

What is the prognosis for patients diagnosed with dermatomyositis?
Dermatomyositis may spontaneously remit in as many as 20% of affected patients. About 5% of patients have a fulminant progressive course with eventual death. However, patients who survive the disease may experience residual weakness and disability. Children with severe dermatomyositis may develop contractures.

How fast does dermatomyositis progress?
The deposits have a high calcium content and tend to be firm, white, or flesh-colored nodules over bony areas which can include the elbows, knees, and extremities. These calcifications often develop within three years of diagnosis but may develop up to 20 years later.
Can you have polymyositis and dermatomyositis?

What causes polymyositis and dermatomyositis?
Polymyositis and dermatomyositis are a disease of muscle featuring inflammation of the muscle fibers. The cause of the disease is not known.

What are the treatment options for polymyositis?
If a tumor is associated with polymyositis, sometimes removing the tumor causes the polymyositis to go away. In children, it may be possible to discontinue prednisone after a year if the polymyositis appears to disappear. Polymyositis tends to be more severe and difficult to treat if the disease affects the patient’s heart or lungs.
