The muscle biopsy, routinely processed, was inconclusive with unspecific non-significant inflammatory alterations and an increased level of lipid droplets (normal myophosphorylase and COX) revealed in Oil Red O staining; no glycogen accumulations were observed in Periodic acid-Schiff (PAS) staining (Figures 1-3).
A. Slight accumulation of lipid droplets in the sarcoplasm (Oil Red O, 200x); B. Detail of slight accumulation of lipid droplets in the sarcoplasm (Oil Red O, 400x).
