Follicular lymphoma (FL)/Burkitt lymphoma (BL) add-on tubes

Methodology: Flow Cytometry

Clinical Significance:
This assay includes one tube with a cytoplasmic bcl-2 antibody and a second with an isotype control, and is added on to the workup virtually all CD10+ mature B cell lymphomas. Assessment of cytoplasmic bcl-2 allows distinction of BL (bcl-2 negative, and usually strongly CD38+) from other follicle center-derived B cell lymphomas usually bcl-2-positive, with highly variable CD38). Since CD11c is almost never expressed in FL or BL, if one detects a CD10+/CD11c+ B cell neoplasm, one should strongly consider CD10+ hairy cell leukemia, which is reported to represent ~15% of classic hairy cell leukemia. This tube includes antibodies to CD45, bcl-2, CD10, CD19, CD5, CD20, CD11c, and CD38.
