Abstract
- Renal infiltration is common in chronic lymphocytic leukemia (CLL), but renal impairment caused by leukemic infiltration is rare. This report describes the case of a 38-year-old man with CLL who required no medical treatment for 1 year and was admitted with nonoliguric renal insufficiency (proteinuria > 2,000 mg/day). A renal biopsy subsequently revealed leukemic infiltration by CLL. Treatment with fludarabine plus cyclophosphamide resulted in the improvement of renal function. Leukemic infiltration should be considered in the differential diagnosis of a patient with CLL and impaired renal function because renal impairment often responds well to chemotherapy.
