Abstract
BACKGROUNDRenal involvement in lymphoma is commonly associated with widespread nodal or extranodal lymphoma. Primary renal diffuse large B-cell lymphoma is an extremely rare extranodal lymphoma, accounting for fewer than 1% of all renal masses. Interestingly, the patient in this study had a renal vein tumor thrombus that was observed after laparoscopic radical nephrectomy.CASE SUMMARYWe report the case of a 56-year-old female patient with primary renal lymphoma and a renal vein tumor thrombus whose first symptom was right pain in the back and gross hematuria. Histopathology revealed primary renal diffuse large B-cell lymphoma. The patient received 8 standard cycles of rituximab with cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy after surgery, and no obvious signs of recurrence were observed during the one-year follow-up.CONCLUSIONWe evaluated comprehensive treatment of primary renal diffuse large B-cell lymphoma and multidisciplinary management of this malignancy.
