The patient also received blood products during his hospital stay. Fluorescent in-situ hybridization (FISH) on lymph node biopsy confirmed the rearrangement of MYC and BCL2 genes, indicating the diagnosis of high-grade B-cell lymphoma (HGBCL) (Table 2 and Figure 5). Here, MYC is linked to B-cell non-Hodgkin lymphoma.
