The pathology was follicular lymphoma grade 1: centrocyte or centroblast-like lymphoid cells in ill-defined geminal center-like structures (Figures 4A-4B) were positive for CD20 (Figure 4C), negative for CD3 (Figure 4D), positive for CD10 (Figure 4E), BCL2 (Figure 4F), and BCL6 (Figure 4G). Here, MME is linked to follicular lymphoma.
