Histopathologic finding on muscle biopsy. (a) H&E: large group atrophy (atrophic muscle, an issue surrounded by other normal appearances of fascicles or scattered angular atrophic fibers). (b) ATPase reaction aspects of type-grouping, typical neurogenic muscular atrophy; muscular fascicle and the atrophic consisting of a single type of fiber; in this case type I and the other parts are nearly all composed of fibers of type II. (c) Oxidative reaction SDH aggregates subsarcolemmal hyperchromatic, crescent-shaped, which correspond to the accumulation of mitochondria.
