The distribution of medical histology is as follows: diffuse large B-cell lymphoma not otherwise specified (DLBCL-NOS, n = 20); primary mediastinal large B-cell lymphoma (PMBL, n = 6); transformed DLBCL (n = 2); primary breast DLBCL (n = 1); and high-grade B-cell lymphoma (MYC, BCL2, and BCL6 rearrangement, n = 1). Here, BCL2 is linked to B-cell non-Hodgkin lymphoma.
