Intrafollicular neoplasia/“in situ” follicular lymphoma. In another case with several affected follicles, the number of BCL2⁺ cells is variable, whereas the BCL2 staining is consistently high and uniform (A). The proliferation is limited to the follicular areas, as demonstrated by CD10 (B) and BCL6 (C) and the proliferation rate is low (D). Immunoperoxidase, hematoxylin counterstain. Images were taken using a Nikon Eclipse 80i microscope (Nikon) with a Pan Fluor 4×/0.13 objective and Nikon digital sight DS-Fi1 camera equipped with control unit-DS-L2 (Nikon). Images were assembled using Adobe Photoshop 6 (Adobe Systems).
