CLL and SLL are different manifestations of the same disease; SLL is diagnosed when the disease is mainly nodal, and CLL is diagnosed when the disease is seen in the blood and bone marrow. Patients with < 5000 B lymphocytes/µL and lymphadenopathy but no cytopenias are more likely to have SLL rather than CLL, although lymph node biopsy should be performed to confirm this diagnosis.
