Symptoms arise from tumor infiltration and monoclonal protein production. Here, we present a case of CLL transforming into WM during treatment with ibrutinib. Given the rarity of such a transformation, this case may serve as a valuable reference, and further investigation is needed to understand the pathology underlying this transformation.
In conclusion, we uncovered new insights into the mutational landscape of WM, depicting a more complex involvement of the NF-kB pathway, and providing evidence of the recurrence of some variants (MYD88, IL17RB, NFKB2, ATM, CARD11, PTPN13, and WNK2) also in IgM MGUS.
This association will assist in identifying a target population that may benefit from MYD88-specific treatment regimens. This may exponentially improve the outcome of patients with DLBCL harboring this mutation.

MYD88 (MYD88 Innate Immune Signal Transduction Adaptor)
The phase 3 ASPEN study compared the efficacy and safety of zanubrutinib with ibrutinib in patients with WM. While further investigation is required, this analysis supports the potential use and further exploration of Bruton tyrosine kinase inhibitors to treat PN symptoms in patients with WM. ClinicalTrials.gov: NCT03053440.

MYD88 (MYD88 Innate Immune Signal Transduction Adaptor)
Through this case, we reviewed relevant studies, which indicated that MYD88 mutations, along with other genetic anomalies, may play a significant role in this process. In the future, it is essential to collect more of these rare cases for further research.

MYD88 (MYD88 Innate Immune Signal Transduction Adaptor)
In conclusion, our study highlights a high prevalence of MYD88 and CD79B mutations in PSDLBCL, identifying an aggressive MCD-like subtype with a distinct relapse pattern. This molecular subclassification can be helpful for both prognostic prediction and therapeutic strategy in patients with PSDLBCL.
Even MYC-R cases showed better prognosis. Further studies involving a large series of LBCLs in extranodal organs are needed to expand on the findings of this study.
Our findings indicate a high frequency of MYD88 L265P mutations in our study population and not associated with prognostic markers or the outcome of the disease.

Testing for MYD88 mutations using AS-PCR or ddPCR in unsorted samples is viable for routine clinical practice. Under BTKi treatment, MYD88 and CXCR4 mutations hold greater prognostic importance than IPSSWM staging in WM.
IGLL5, MYD88, and KMT2D mutations were enriched in Taiwanese CLL, and co-occurrence of MYD88 mutations with KMT2D or/and IGLL5 mutations was associated with a poorer prognosis.
