  ) Hypocellular mass with spindle-shaped and stellate cells scattered within a mucopolysaccharide myxoid matrix (H&E, Scale bar = 100 microm. Inset: High magnification of spindle-shaped cells in a myxoid matrix (H&E, Scale bar = 20.00 microm), B) Myxoid cells display a periodic acid Schiff positive cytoplasm (arrowheads), (PAS, Scale bar = 20.00 microm).

case_images: Stellate-to-reticular cells distributed in a mucinous stroma containing few tiny blood vessels were seen (Fig. 2A). Myxoid cells displayed a PAS positive cytoplasm and round to oval nuclei and the stroma was stained pale positive with PAS, indicating the presence of glycosaminoglycan in the myxoid mass (Fig. 2B).
case_images: The intercellular myxoid matrix (arrowheads) is alcianophilic at the pH of 2.50 (Alcian blue, Scale bar = 20.00 microm)
