- Chronic lymphocytic leukemia must be differentiated from other diseases that cause weight loss, night sweats, hepatosplenomegaly, and palpable lymph nodes, such as hairy cell leukaemia, prolymphocytic leukaemia, follicular lymphoma, and mantle cell lymphoma.
- The table below summarizes how to differentiate chronic lymphocytic leukemia from other conditions that cause similar presentation:[1]

- Chronic lymphocytic leukemia must also be differentiated from other causes of fever, hepatosplenomegaly, and lymph node swelling such as:
- Splenic marginal zone lymphoma
- Nodal marginal zone lymphoma
- Lymphoplasmacytic lymphoma
- Sézary syndrome
- Smoldering adult T cell leukemia[2]
