Description
Juvenile dermatomyositis (JDM) is a disease in children that causes skin rash (dermato) and muscle inflammation (myositis) resulting in muscle weakness. JDM is an autoimmune disease, although genetic and environmental influences are thought to play a role. The diagnosis can be confirmed by finding JDM-associated autoantibodies.
