Figure 4: Hematoxylin and eosin ×400 (a) sections show fragments of neoplasm composed of tumor cells in diffuse sheets along with extensive crushing artefact. Tumor cells have moderate cytoplasm, large vesicular nuclei, small nucleoli. CD20 ×400 (b): Tumor cells are CD20 positive. ×400 (c): Tumor cells are BCL6 positive. ×400 (d): Tumor cells have a high MIB1 labeling index of 80%
