These rarely occur, and most common renal manifestations are mild proteinuria and microscopic hematuria. Herein we describe a case of WM that presented with pseudothrombi depositing in capillaries associated with minimal change nephrotic syndrome and chronic kidney disease(CKD).CASE SUMMARY A 52-year-old man presented with features suggesting nephrotic syndrome.Extensive workups were done, and there were elevated serum levels of interleukin-6 and vascular endothelial growth factor(VEGF), capillary pseudothrombus accumulation associated with minimal change nephrotic syndrome, CKD, and WM. Treatment was directed at the patient’s WM with bortezomib, thalidomide, and dexamethasone whereby serum immunoglobulin M(IgM) decreased. The damage of IgM on the kidney was corrected; thus, the patient’s proteinuria and serum creatinine had improved. The patient is still under clinical follow-up.CONCLUSION It is essential for clinicians to promptly pay more attention to patients presenting with features of nephrotic syndrome and do extensive workups to come up with a proper therapy strategy.展开更多

Higher-grade non-Hodgkin lymphoma （NHL） and therapy- related myelodysplasia/acute leukemia （t-MDS/AML） have been reported in patients with WM/LPL in previous studies. However, only two cases with WM/LPL were reported to develop to Hodgkin lymphoma （HL）. Here, we report the first case of WM/LPL who developed classical HL simultaneously 3 years after initial nucleoside analog-based chemotherapy.展开更多
