Hematology, oncology. Large granular lymphocytic (LGL) leukemia is a chronic lymphoproliferative disorder that exhibits an unexplained, chronic (> 6 months) elevation in large granular lymphocytes (LGLs) in the peripheral blood. It is divided in two main categories: T-cell LGL leukemia (T-LGLL) and natural-killer (NK)-cell LGL leukemia (NK-LGLL). Indolent T-LGL leukemia is the most frequent form of the disease representing ∼85% of the cases, whereas chronic NK-cell lymphocytosis is estimated at <10% of cases. Aggressive NK-LGL leukemia is mainly seen in Asia and comprises <5% of the LGL disorders. Furthermore, virtually all the natural killer (NK) activity of LGL was associated with OKT11+ and OKM1+, DR+ LGL that exerted the observed APC function, suggesting that NK-active cells may also act as effective APC for T lymphocyte activation.

disorders: T-cell LGL (T-LGL) leukemia, chronic lymphoproliferative disorders of NK cells (CLPD-NK) 25 Nov 2020 Large granular lymphocyte (LGL) leukemia has been recognized by the WHO classifications among mature T cell and NK cell neoplasms. STAT3 and STAT5B Mutations in T/NK-Cell Chronic Lymphoproliferative Disorders of Large Granular Lymphocytes (LGL): Association with Disease Features.

T-cell clonality – Genetic testing for evidence of T-cell clonality (genetically identical cancer cells) is needed to distinguish clonal cancer T-LGL leukaemia cells from normal T-LGL cells. This test is not useful for NK-LGL leukaemia cells which can make the diagnosis challenging in this situation.

4 | EBV+ T- CELL AND NK- CELL LYMPHOMAS 4.1 | Aggressive NK-cell leukaemia This is a very aggressive form of leukaemia derived from activated NK cells and strongly associated with Epstein-Barr virus (EBV). Although the immunophenotype is very similar to that of extranodal T/NK from NK-LDGL the entities of NK-LGL, chronic lymphoproliferative disorder of NK cells (CLPD-NK), and ANKL.

H&O How does LGLL manifest?. LN Large granular lymphocytic leukemia (LGLL) is an uncommon lymphoproliferation of mature cytotoxic T cells or natural killer (NK) cells.The disease is characterized by cytopenias, which contribute to the majority of the morbidity. LGLL generally affects elderly patients and is often associated with an underlying autoimmune disease, such as rheumatoid arthritis

Each type may be chronic (slow-growing) or aggressive (fast-growing). LGL leukemia affects both men and women. 2021-4-2 · Your blood contains two different types of lymphocytes: T-cells (T-LGL) and B-cells, which are also known as natural killer cells (NK-LGL). B-cells fight off invading bacteria and viruses. T-cells In 1989, the French-American-British classification identified LGL leukemia as a distinct entity among chronic T-lymphoid leukemias.. In 1993, the distinction was made between CD3 + T-cell and CD3 − NK-cell lineage subtypes of LGL leukemia..

They may be either T cells (T-LGL), the more common type, or natural killer cells (NK-LGL) [ 1,2 ]. LGL leukemia is a heterogeneous disorder characterized by peripheral blood and marrow lymphocytic infiltration with LGLs, splenomegaly, and cytopenias, most commonly neutropenia. T-cells NK-cells Types of Lymphocytes In LGL leukemia, T- or NK-cells become clonal (make copies of themselves). The different markers indicate which cell is clonal.
