  • Title: Centronuclear myopathy with unusual mitochondrial abnormalities.
    Author: Canal N, Comi GC, Comola M, Testa D, Mora M, Cornelio F.
    Journal: Clin Neuropathol; 1985; 4(1):23-7. PubMed ID: 2983917.
    Abstract:
    The case of a 34-years-old man is described with a progressive myopathy characterized by limb weakness and atrophy, involvement of facial, masticatory and extraocular muscles. The prominent features of the muscle biopsy were the presence of centrally located nuclei in most fibers. There was also an atrophy and predominance of type I fibers. Both clinical and morphological features were consistent with the diagnosis of centronuclear myopathy. Electron microscopic studies showed the presence of mitochondria with paracrystalline inclusions near the centralized nuclei but not in the subsarcolemmal position. This hitherto unreported feature led the authors to re-evaluate the hypothesis on the pathogenesis and the nosological classification of this myopathy.
