Interestingly, some of the other antigens present might suggest a specific genetic subtype of B-lymphoblastic leukemia, which also might have a certain prognosis. Now, if an adult has a small number of mature B cells but also has a large number of immature B cells which are positive for CD19 (remember, CD19 is a B-cell marker) and also positive for both CD34 and CD20 (which identifies those cells are both immature and abnormal), then the personhasan immature B-cell leukemia known as B-lymphoblastic leukemia. It is not offered in every laboratory, but many larger hospitals and academic medical centers perform the testing or your sample may be sent to a reference laboratory.

Using a method of analysis relying solely on immunoarchitectural features of a given case, the authors were able to define immunologic criteria capable of differentiating benign from malignant lymphoid processes independent from conventional morphologic analysis. In addition to reflexing flow cytometric panels, acute myeloid leukemia (AML) fluorescence in situ hybridization (FISH) testing for PML-RARA translocation t(15;17) may be added by the Mayo Clinic pathologist to exclude acute promyelocytic leukemia if there is morphologic suspicion or if blasts and promyelocytes are CD34-negative and HLA-DR-negative.

Non-Hodgkin's lymphoma presenting as a primary cardiac lymphoma (PCL) is extremely unusual. This triage panel also determines if there is an increase in the number of T cells that aberrantly coexpress CD16, an immunophenotypic feature of T-cell granular lymphocytic leukemia. Rarely, no overt immunophenotypic abnormality will be present at diagnosis, and in these cases, the sensitivity of flow cytometric evaluation for minimal residual disease may be greatly reduced. Report will include a morphologic description, a summary of the procedure, the percent positivity of selected antigens, and an interpretive conclusion based on the correlation of the clinical history with the morphologic features and immunophenotypic results. Additional FISH or molecular testing may be recommended by the Mayo pathologist to facilitate diagnosis. If .

Our results present evidences of an abnormal B-cell maturation in MDS. Front Oncol. Because of this, immunophenotyping results will be different by reflecting the current population of WBCs that would be present in an individual in remission. Disclaimer.
