The study included ten cases of pure EZB genetic subtype diffuse large B-cell lymphoma, which comprised germinal center B-cell (GCB) type DLBCL NOS, high-grade/DLBCL double-hit (DH) lymphoma characterized by MYC and BCL2 rearrangements (three cases), as well as rare B germinal center-derived DLBCL subtypes, including T-cell/histiocyte-rich B-cell lymphoma. Here, BCL2 is linked to lymphoma.
