Figure 2: (a) Scanner view (H and E, ×40) showing haphazard pattern of tumor-islands of closely set hyperchromatic basaloid cells in desmoplastic stroma, (b) High power view (H and E, ×200) of the tumor-islands showing hyperchromatic round to oval basaloid tumor cells and their characteristic peripheral palisading along with easily observed mitoses within individual tumor cells, (c) Tumor cells showing nuclear staining for p63 marker (H and E, ×40), (d) Tumor cells showing strong cytoplasmic reactivity for p16 (H and E, ×40), (e) Tumor showing weak membranous staining for Ber-Ep4 (H and E, ×200), and (f) Tumor showing absent staining for Bcl2 (H and E, ×200); scattered lymphocytes in the stroma are positive for the stain
