Histological and ultrastructural alterations of skeletal muscles in Duchenne muscular dystrophy (DMD) (32 cases) and polymyositis (PM) (33 cases) were compared qualitatively and quantitatively. Regeneration is more numerous in PM than DMD throughout all stages. Stromal fibrosis and hyaline fiber with delta lesion are characteristic for DMD. In the electron microscope, we observed the usual preservation of basement membrane in degenerating muscle fibers and uncomplicated muscle regeneration in… CONTINUE READING
