a) May-Grunwald-Giemsa (MGG) stained preparations appearing moderately cellular and forming multiple large, irregular, cohesive clusters of ovoid or spindle tumor cells. b) Clusters consisting of oval or elongated, bland nuclei and thin semitransparent, vacuolated, clear cytoplasm and showing positivity with the periodic acid-Schiff (PAS) method owing to the glycogen (sugar) content.

The cytologic preparations were moderately cellular and showed multiple large, irregular, cohesive clusters of ovoid or spindle tumor cells (Fig. 1a) These clusters consisted of oval or elongated, bland nuclei and thin semitransparent, vacuolated, clear cytoplasm, which showed positive staining by the periodic acid-Schiff (PAS) method owing to the glycogen (sugar) content (Fig. 1b).
a) Microscopy of the tumor revealing neoplastic cells arranged in insular patterns and separated by a rich delicate capillary network and sinusoid-like vessels (magnification x 10). b) On higher magnification, cells appearing epithelioid-like with round or ovoid, polymorphic nuclei, apparent nucleoli and pale, vacuolated or clear cytoplasm (magnification x 40).

Microscopy of the tumor revealed neoplastic cells arranged in insular patterns and separated by a rich delicate capillary network and sinusoid-like vessels (Fig. 2a). On higher magnification, cells were epithelioid-like with round or ovoid, polymorphic nuclei, apparent nucleoli and pale, vacuolated or clear cytoplasm (Fig. 2b).
