Biceps brachii muscle biopsy from patient. A There is variation in fibre size consistent with a chronic myopathy. B No inclusions are seen on Gömöri-trichrome stain. C and F Some fibres showed pale central areas on NADH stain and SDH stains (arrows) but not on E COX staining, suggesting regions with reduced oxidative enzyme activities. D There is predominantly type 2 fibre atrophy with no fibre type predominance. (A: Hematoxylin and eosin (HE) stain, original magnification × 10; B: Gömöri-trichrome stain, original magnification × 20; C: NADH-TR stain, original magnification × 10; D: ATPase pH9.4, original magnification × 10; E: COX stain, original magnification × 10; F: SDH stain, original magnification × 10; A-F: scale bar 100mm; picture resolution A-F: 1280 x1024)
