It can be used for identifying the lineage of the cell in smears of tissues with suspected lymphoma or histocytic sarcoma. MDS is distinguished from other disease processes by a pattern of multiple myeloid immunophenotypic abnormalities (3-6). Among T-cell populations outside the thymus, phenotypes associated with malignancy included 1) loss of pan-T antigens (including loss of the beta chain of the T-cell antigen receptor), 2) coexpression or loss of T-subset antigens, 3) Leu-6+ T-lineage, and 4) MB-1+ T lineage. Application of these criteria to a series of nearly 500 cases of lymphoma indicated that over 90% of B-lineage and about 80% of T-lineage neoplasms manifested immunophenotypic abnormalities that could distinguish them from benign, reactive lymphoid processes. First, the CD45/linear side scatter gating of flow cytometry allows the initial identification of neoplastic subpopulations for additional immunophenotypic analysis in half of ANKL cases.

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. Table 1. Conclusion: Only 5 similar cases have been described previously. Accessed December 2014. 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. Flow cytometry is generally used to determine cell lineage in leukemia and lymphoma. 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.
