BCL2 and B-cell non-Hodgkin lymphoma: For that reason, we investigated the expression pattern of H3K27m3 and EZH2 in 148 FL cases (daily routine excisional biopsies and tissue micro-arrayed cases) of all grades, both BCL2-positive and BCL2-negative as well as BCL2-rearranged and not-rearranged, in 9 primary cutaneous follicle center lymphomas (PCFCL) and 5 pediatric-type FL (PTFL) and compared the staining results to a control cohort of various reactive conditions and different B cell lymphomas.
