case_images: Pleomorphic large vesicular cells scattered randomly or grouped which have immunoblastic morphology with significant nucleolus between small lymphocytic and histiocytic cells were demonstrated (Figure 2(a)). Immunohistochemical examination revealed CD 20 positivity in these large cells (Figure 2(b)). Ki 67 proliferation index was 60% (Figure 2(c)).
