I agree with Mary. Cases of Follicular lymphoma that are (sIg -) are rare. If you trust that the antibodies were properly added and still sees no or marginal expression (polyclonal) along with strong expression of CD10/CD19/CD20, it will most likely be a Follicular Lymphoma. I am attaching the dotplots in a word file (flow.doc) of a recent case. In this case, not only the surface Ig were negative, but also the cytoplasmic were negative as well. Only 6% of the B cells expressed either Kappa or Lambda light chain. <<flow.doc>> Safwat Girgis Pasqua Hospital Laboratory Medicine 4101 Dewdney Avenue., Regina SK S4T 1A5 Tel: 306 766 2229 Fax: 306 766 2752
