Figure 2:(a) Fine-needle aspiration smear showing proliferation of hyperchromatic spindle cells (arrow) in background of stroma and inflammatory cells. (×400); (b) Section showing proliferation of spindle cells and necrosis with rich vascularity. (×100); (c-e) spindle shaped cells with moderate to marked anisonucleosis and rich vascularity. (×400); (d) focal matrix and stromal hyalinization (arrow). (×400); (f) strong cytokeratin cytoplasmic expression. (×400); (g) Epithelial membrane antigen positivity with internal control (×100); (h) strong vimentin positivity. (×400)
