Am J Blood Res. Flow cytometry may be used to characterize and count types of white blood cells in the evaluation of infectious diseases, autoimmune disorders or immunodeficiencies. Immunocytochemistry is, however, limited by the quality and number of smears as one antibody is applied to one smear. An abnormal plasma cell population is detected that is positive for CD38, and CD56. Among B-lineage populations the following features were associated with malignant histology: 1) light-chain-restricted B lineage, 2) light chain -B lineage, 3) Leu-1+ B lineage, 4) L60+ B lineage, 5) 41H+, Ki-67+ B lineage, 6) loss of pan-B antigens, and 7) LFA-1-B lineage. The third parameter for assessing dysplasia by flow cytometry is maturation pattern of granulocytes on CD13/CD16 plot. The abnormal cells grow, but they do not fight infections or perform other functions like normal WBCs. In patients with RAEB-t and CMML no CD34+ B-cell precursors could be detected.

Detection of Bcell populations with monotypic light chain expression Second, unusual expression of surface antigens in ANKL cells was a prominent feature. In the current study, we report the clinical, laboratory, immunophenotypic, and genetic findings from 29 cases of de novo ANKL in a single center and evaluate the relative contribution of these features to the diagnosis of ANKL. More importantly, there are newer classes of treatment options like CAR-T therapy, bispecific T-cell engagers, and monoclonal antibodies thatselectively target molecules like CD19 or CD20.
