Like conventional DLBCL/HGBCL‐MYC/BCL2, the TdT‐positive cases with MYC/BCL2 translocation harboured a characteristic mutation profile, including mutation signatures associated with FL and also its high‐grade transformation [8, 9, 10, 11, 12]. The gene discussed is BCL2; the disease is diffuse large B-cell lymphoma.
