Figure 5

Morphological features of nasal tumor. (a) Low-power view shows diffuse cellular infiltrates with necrosis and mucosal ulcer (H&E, 100x). (b) High-power view shows a mixture of small-, medium-, and large-sized cells with angiocentric growth pattern (H&E, 200x). Immunohistochemical study: (c) the tumor cells are positive for granzyme B (C). Nuclei are positive for EBER by in situ hybridization (d) (400x).
