Abstract
Immune-mediated necrotizing myopathy (IMNM), also known as necrotizing autoimmune myopathy, is a histologic entity characterized by marked necrosis in the absence of prominent lymphocytes.1 Risk factors or triggers for IMNM include statin treatment, cancer, and connective tissue disease (CTD).1,2 Although autoantibodies against signal recognition particle (SRP) or 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) are regarded as markers for IMNM, they are not always detected in sera of pathologically defined patients with IMNM. The autoimmune mechanisms of IMNM are not elucidated.
