Necrotic myopathy – http://id.who.int/icd/entity/124501922

Group of myopathic disorders characterized by the predominant pathological feature of necrosis of muscle fibers in the absence of substantial lymphocytic inflammatory infiltrates. Most commonly divided into immune-mediated (IMNM) and non-immune mediated (NIMNM). Both IMNM and NIMNM are typically characterized by proximal weakness, although the severity can vary.
