Immune-mediated necrotizing myopathy (IMNM) is a type of autoimmune myopathy characterized by relatively severe proximal weakness with high serum muscle enzyme levels, myofiber necrosis with minimal inflammatory cell infiltrate on muscle biopsy, and infrequent extra-muscular involvement. The mechanism of necrotizing myopathy remains unclear. The new European Neuromuscular Centre criteria divides IMNM into three distinct subtypes according to different autoantibodies, which reminds us antibodies may be involved in the pathogenesis of IMNM and different subtypes may have different pathogenesis. This review summarizes the current understanding of the pathogenesis of IMNM.
