The lesion was partially cystic with thickened walls and an intralesional solid component (Figure 1).
Mixture of highly atypical spindle and giant cells. The larger cells often contain numerous intracytoplasmic hyaline globules (hematoxylin and eosin, 20x magnification).

Microscopically, the tumor was composed of stellate or spindle shaped cells with bizarre morphology and ill-defined outlines, loosely arranged in an abundant myxoid matrix (Figure 2).
Tumor cells show strong membranous expression of CD10 (CD10 immunohistochemistry, 20x magnification).

Immunostainings revealed CD10, CD68, and vimentin expression in tumor cells, with focal and weak expression of wide spectrum cytokeratins (AE1/AE3) (Figure 3).
