Three cases of nemaline myopathy are reported. The first one was characterized by delayed motor milestones, hypotonia and proximal weakness in a 2-year-old girld. The second case was diagnosed at 19 in a boy who suffered from a severe scoliosis without any neurological sign. The third patient was a 31 year-old man who had a progressive muscular weakness of limb girdles. Muscle biopsy revealed rods in muscle fibers with Gomori trichrome staining in two cases, and by electron microscopy in one case only. Variations of fiber calibration, fiber I predominance and a myofibrillar disorganization were seen in two cases. Clinical, histopathological and physiopathological of nemaline myopathy are discussed.

D008297 Male Males
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
