DLBCL : Immunophenotype
Diffuse large B-cell lymphoma : Immunophenotyping by flow cytometry (same case as the previous image). The large lymphoid cells (colored orange) are identified in this CD45 vs side scatter (SS) plot. SS is a measure of cell complexity (caused by cytoplasmic and nuclear components). Additional studies showed expression of CD19, CD20 and surface kappa light chains (see next image). The normal lymphocytes are circled blue. Image courtesy of : Dr. Kali Freeman, Hematopathologist, Yosemite Pathology Medical Group, California, USA.
