(a) Frozen section, H&E stain, showed mild fiber size variation and increased central nuclei. (b) Frozen section, H&E stain, demonstrated chronic fibrosis, fiber size variation, occasional central nuclei, and scattered degenerating and regenerating fibers. (c) Frozen section, Gomori trichrome stain, revealed occasional rimmed vacuoles (arrow). (d) Frozen section, nonspecific esterase (NSE) stain, also revealed occasional tubular aggregates (arrow). (e) Frozen section, NADH-tetrazolium reductase (NADH-TR) stain, revealed occasional tubular aggregates.
