Fig. 3From: B cell-rich non-neoplastic sentinel lesion preceding primary central nervous system lymphomaComparative immunohistochemistry between the first and second biopsies. See “Case presentation” section for description. Of note, the vessel shown in the CD20/3/5/10 panels from the first biopsy was adjacent to the vessel shown in the Ki67/EBER panels, due to the original vessel diminishing on deeper sectioning.
