Muscle segment examination in light and electron microscopy

Abstract:

A 21-year-old patient with suspected polymyositis was examined. A biopsy of quadriceps sinisterwas performed.Electronmicroscopy analysis revealed increased glycogen accumulation within muscle fibers andpreserved sarcomeres structure. Focally large deposits of glycogen were seen (Fig.1,2).Vacuoles containing glycogen and an average number of fat droplets were seen.Glycogen-filled vacuoles may suggest a late glycogenosis type II, but PAS, PAS-diastase andphosphorylase were within the normal range.Limb-girdle dystrophy with dysferlin defect is suspected.
