title: Renal involvement of mantle cell lymphona leading to end stage renal disease.
abstract: Mantle cell lymphoma (MCL), owing to its insensitivity to chemotherapy, has a poor prognosis, with a median survival of 3 years to 4 years. MCL frequently infiltrates other organs. However, reports involving kidney in living patients are rare. Here, we report a case of MCL with renal involvement leading to end stage renal disease that required renal replacement therapy. A 69-year-old man diagnosed with MCL 3 years earlier was admitted to our emergency room due to uremic symptoms. After eight cycles of chemotherapy, he had displayed complete remission, but experienced a recurrence 1.5 years later; after refusing chemotherapy, the patient was lost on follow-up in the final 10 months. On presentation at the emergency room, the patient's serum blood urea nitrogen was 109.5 mg/dL, and creatinine was 11.1 mg/dL. All serological markers for secondary glomerulonephritis were negative. Renal biopsy revealed 50% sclerosis of the glomerulus and small dense lymphocyte infiltration of the tubulo-interstitium. Similar cells were found on the gastric mucosa. Despite our recommendation for chemotherapy, he refused all treatments except for hemodialysis, which was maintained for 12 months until his death. This patient represents the first case report of the renal involvement of MCL leading to end stage renal disease.
