Polymyositis is a type of chronic muscle inflammation related to dermatomyositis and inclusion body myositis; its name comes from the Greek for many, muscle and inflammation. The inflammation is found mainly in the endomysial layer of skeletal muscle, in contrast to dermatomyositis, which is characterized primarily by inflammation of the perimysial layer.
