Abstract
Estudamos 16 casos entre 1400 biópsias musculares que apresentavam vacúolos marginados, cujo aspecto histológico sugeria corpos de inclusão citoplasmáticos. Procuramos correlacionar os dados clínicos, laboratoriais e histopatológicos, a fim de determinar a especificidade dos corpos de inclusão citoplasmáticos para determinadas doenças. A creatinaquinase mostrou-se elevada em 10 casos. A eletromiografia foi anormal em todos os casos. A histoquímica muscular em 5 casos revelou uma miopatia, em 7 padrão misto, em dois desinervação e em 2 casos miopatia inflamatória. A microscopia eletrônica demonstrou a presença de filamentos em 8 casos (nucleares, dispersos no citoplasma ou na região subsarcolemal). Os pacientes foram classificados conforme a história clínica, hereditariedade, dados laboratoriais, eletrofisiológicos, histoquímicos e microscopia eletrônica Encontramos miosite com corpos de inclusão citoplasmática (4 casos), atrofia muscular espinhal juvenil (6 casos), miopatias distais (3 casos), distrofia de cinturas pélvica e escapular (2 casos) e polineuropatia periférica (1 caso). Apresentamos revisão sobre a patogenia, formação e possível etiologia dos vacúolos marginados e sua relação com as diversas entidades em que foram detectados, sugerindo que não são específicos para uma única doença.
Among 1400 muscle biopsies, we studied 16 cases with rimmed vacuoles, whose histology suggests cytoplasm inclusion bodies. We tried to correlate the clinical, laboratory and histopatological data in order to verify the specificity of cytoplasm inclusion bodies to certain diseases. The creatinekinase was increased in 10 cases. In all cases electromyography was abnormal. Muscle histochemistry revealed myopathy in 5 cases, mixed pattern in 7, denervation in 2 and in 2 cases, inflammatory myopathy. Electron microscopy showed the presence of filaments in 8 cases (nuclear, disseminated in cytoplasm or in the subsarcolemmal region). The patients were classified according to history, heredity, laboratory, electrophysiologic, histochemistry data and electron microscopy: in myositis with inclusion cytoplasmic bodies (4 cases), juvenile spinal muscular atrophy (6 cases), distal myopathies (3 cases), limb-girdle dystrophy (2 cases) and peripheral neuropathy (1 case). We present a revision on the pathogenesis and possible etiology of rimmed vacuoles and their relationship with several diseases.
