Figure 1: (a) Lymph node biopsy showing cells arranged in follicular pattern with closely packed follicles (H and E x100), (b) Higher magnification of the same showing centroblasts (6 -8/ HPF), with mitotic figures (H and E x400), (c) The neoplastic cells are positive for CD20 (IHC x100), (d) CD3 has stained the reactive cells (IHC x100). (e) Bcl2 positivity in follicles (IHC x 100), (f) High Ki67 index (60%) in neoplastic cells (IHC x100)
