Figure 1: (a) Pleomorphic adenoma: sheets of myoepithelial cells and ductular structures lined by epithelial cells set in chondromyxoid stroma (H&E stain, 100). Myoepithelial carcinoma: Cellular tumor with infiltration of adjacent bone (b) and areas of geographic necrosis (c) (H&E stain, 100). (d) Cells arranged in lobules, nests, trabeculae and cords with hyperchromatic, pleomorphic, mitotically active nuclei (H&E stain, 200); (e) Immunoprofile of myoepithelial carcinoma displaying positivity for S-100 (IHC stain, 100), (f) Cytokeratin (IHC stain, 100) and (g) Focally SMA (inset, IHC stain, 400)
