(a) Flow cytometry of the ungated specimen of the abdominal mass showing a Cd45 bright population, compatible with a lymphoproliferative process (rather than a carcinoma, melanoma, etc.), (b) gating only the CD45 bright/low side scatter population shows a predominant CD20+/CD10+ population, consistent with a B-cell population of germinal center origin, and (c) light chain expression shows lambda light chain restriction, diagnostic of a B-cell lymphoma.
