In 2017, the World Health Organization (WHO) classification categorized high-grade B-cell lymphomas with an MYC rearrangement combined with a BCL2 and/or BCL6 rearrangements separately as double hit high-grade B-cell lymphoma (HGBCL DH) and DLBCL cases with high-grade morphology that lack these concurrent hits as HGBCL NOS [1]. Here, BCL2 is linked to B-cell non-Hodgkin lymphoma.
