A biceps biopsy was performed. Electronmicroscopy analysis revealed ultrastructurally unchanged muscle fibers, characterized by preserved sarcomeres structure and normal mitochondria. Atrophied fibers, characterized by smaller diameter, accumulation of cell nuclei, disrupture/atrophy of the contractile apparatus and sometimes containing deposits of lipofuscin were also observed.Some of the fibers also showed abnormalities in the nuclei structure and / or damage to myofibrils. Infiltration of lymphocytes and plasma cells were observed in the endomysium.Microscopic image of the biopsy may suggest a past inflammatory process .}, title={Files for neuromuscular diseases (2011) - nr 24/11}, type={Text}, type={Image}, URL={http://rcin.org.pl/Content/136508/PDF/24_11_calosc.pdf}, keywords={Polymyositis}, }
