Accordingly, these cases are now designated as a subtype of diffuse large/high‐grade B‐cell lymphoma with MYC/BCL2 rearrangement (DLBCL/HGBCL‐MYC/BCL2, or DLBCL/HGBCL‐MYC/BCL2/BCL6 when an additional BCL6 rearrangement is present) in the fifth edition of the WHO classification of haematolymphoid tumours (WHO‐HAEM5) [7]. This evidence concerns the gene BCL2 and B-cell non-Hodgkin lymphoma.
