Blastoid-HGBL cases had significantly more frequent CD45 expression at an intensity greater than that of granulocytes, dimmer CD10 expression relative to the level of hematogones, brighter CD20 comparable to mature B cells, and brighter CD38 at the level of hematogones (p < 0.01 for all) (Table 1 and Figure 2). Here, MS4A1 is linked to high grade B-cell lymphoma.
