In brief: Autoimmune likely...

Juvenile dermatomyositis (jdm) is an idiopathic inflammatory myopathy (imm) of presumed autoimmune dysfunction resulting in muscle weakness among other complications.
It manifests itself in children; it is the pediatric counterpart of dermatomyositis. In jdm, the body's immune system attacks blood vessels throughout the body, causing inflammation called vasculitis.

Dermatomyositis is not a true vasculitis since it does not involve white blood cells going into the wall of blood vessels. It is a vasculopathy though meaning the disease does involve a disease process involving damage to the blood vessels. It is a severe disease, as severe as lupus at times, and should be managed by a Board Certified pediatric rheumatologist.
