title: [Myopathies associated with tubular aggregates].
abstract: The authors report the case of a 58-year-old male patient with clinical and electromyographic features of myasthenia. Muscle biopsy with histochemistry and electronic microscopy made it possible to diagnose a myopathy associated with tubular aggregates. Attention is called to the fact that the anatomical pathologic alterations which were found may be present in a heterogenous group of patients showing a great variety of symptoms. Thus, there is no reason to consider the existence of a myopathy associated with tubular aggregates, since the anatomical and pathologic findings are inespecific and do not characterize any specific disease.
