title: Renal failure due to T-cell mediated lymphocytic vasculitis: an unusual complication of B-cell chronic lymphocytic leukemia.
abstract: Vasculitis is an uncommon paraneoplastic syndrome, and acute renal failure is an unusual presentation of leukemia. We report a case of B-cell chronic lymphocytic leukemia that presented with acute renal failure caused by biopsy-proven lymphocytic vasculitis that subsequently was shown to be T-cell-mediated and systemic at autopsy.
