Introduction:
Pediatric B non-Hodgkin lymphoma (B-NHL) often presents with complex karyotypes (CK), co-occurring high-risk mutations, and treatment resistance, leading to poor outcomes.
Case Description:
We describe a child with a CK including MYC::IGH translocation, MYC inversion, TP53 deletion, BCL6 gain, and BCL2 loss, exhibiting a high tumor burden and a partial response to standard therapy, requiring treatment intensification.
Conclusion:
This case emphasizes the critical role of comprehensive cytogenetic and molecular profiling to guide diagnosis, risk stratification, and therapy selection. Recognition of high-risk genetic features can inform early intensification or targeted approaches. Pediatric MYC-rearranged B-NHL with complex cytogenetics remains under-characterized but clinically aggressive, underscoring the need for multicenter studies to define its genetic spectrum, refine prognostic models, and optimize individualized treatment strategies.
