$Fig. 3. Different patterns of expression of Ki67, p27KIP1, and BCL6 in lymphomas. / (A) p27KIP1 staining in nontumoral lymphoid tissue (a reactive tonsil). (B) BCL6 and (C) Ki67 in the same sample. (D) A B-CLL case with a high level of p27KIP1 expression. (E) Absence of BCL6 in the same sample and Ki67 (F), in this case, indicating the low-growth fraction of this tumor. (G) A DLBCL case showing absence of p27KIP1 in tumoral cells, with high levels of BCL6 (H) and Ki67 (I) expression. (J) An aggressive DLBCL case showing p27KIP1 overexpression associated with high levels of BCL6 (K) and Ki67 (L). Original magnifications, × 400.$
