Burkitt lymphoma BL a highly aggressive B-cell lymphoma represents approximately 25 of all non-Hodgkin lymphomas NHLs.
This test is usually done after atypical results are seen on a complete blood count or white blood cell WBC differential. The most common type of pancreatic lymphoma was large B cell lymphoma followed by follicular lymphoma. Immunophenotyping by flow cytometry is a sensitive method for detecting residual or recurrent disease in the peripheral blood of patients with an established diagnosis.
With the aid of flow cytometry and immunohistochemical work-up on cell block 72 1825 of the cases were diagnosed as lymphoma and 16 of the cases 425 were diagnosed.
