Idiopathic Inflammatory Myopathies
Major pathology consists of focal inhomogeneous infl ammation with injury, death, and repair of muscle cells.
Each subgroup of myositis has characteristic changes on microscopy and immunochemistry.
■ Etiology is still unclear but selected environmental exposures in genetically predisposed hosts have been found.
