摘要
BACKGROUND Renal 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 SUMMARY We 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.CONCLUSION We evaluated comprehensive treatment of primary renal diffuse large B-cell lymphoma and multidisciplinary management of this malignancy.
