The histopathologic findings of skeletal muscle biopsy specimen in AD EDMD2 (A) and LGMD1B (B-D) patient. (A) Myofibers are reduced in number and replaced by fibroadipose tissues. There are atrophic or hypertrophic myofibers, internalization of sarcolemmal nuclei and fiber splitting (hematoxylin and eosin stain, ×200). (B) Variation in myofiber size, frequent internal nuclei and fatty ingrowth are noted in hematoxylin and eosin stain (×200). (C) ATPase pH 4.6 stain reveals atrophy of type 1 fibers (dark brown stain, ×200). (D) ATPase pH 9.4 stain reveals a predominance of type 2 fibers (brown stain, ×100).
