Chronic Lymphocytic Leukemia

MBL Case: Clinical History

October 2008

I do want to share with you a case of MBL. This was a 66 year old female who presented with a normal CBC and a normal lymphocyte count. The blood smear was normal, and no adenopathy or organomegaly was found in the physical exam. A flow study was performed on the peripheral blood.

After reviewing the chart, I still have no idea why the flow study was originally ordered. After our findings, the patient was evaluated in clinical hematology and a bone marrow study performed.
