About 85 percent of normal LGLs have an NK cell phenotype, and … 2018-05-23 T‐cell neoplasms such as ALCL may show cytoplasmic vacuoles, while T‐LGLL, CLPD‐NK, ENKTCL, and aggressive NK‐cell leukemia are characteristically comprised of cells with granular cytoplasm. Last, but not least, it is important to make a note of the criteria used for calling an antigen positive or negative in a particular population. Large granular lymphocytes (LGL) comprise about 10-15% of normal peripheral blood mononuclear cells. Morphologically they are larger than a normal lymphocyte and have a reniform nucleus with azurophilic granules in their cytoplasm. LGL can be further divided into CD3- NK cells and CD3+ activated cytotoxic T cells depending on their cell lineage. LGL leukemia arises most frequently from a T cell lineage (85 percent) or, less commonly, from a natural killer (NK) cell lineage (15 percent) . The etiology, clinical features, diagnosis, and treatment of NK cell LGL disorders will be discussed here.

Although LGL can be associated with other entities, such as AA or MDS, it is a distinct clinical entity with a specific diagnostic pathway [83,84] . LGLs comprise 10 to 15 percent of normal peripheral blood mononuclear cells. The absolute number of LGLs in the peripheral blood of normal subjects is 0.2-0.4×10 9 /L. LGLs arise from two major lineages.

The different markers indicate which cell is clonal. Previous content described how a diagnosis is made for either case, but briefly, it is based on the cell markers (CD proteins) and for T-LGLL the TCR gene LGLs comprise 5 percent of the population of peripheral blood mononuclear cells, are larger than most circulating lymphocytes, and have characteristic azurophilic granules containing acid hydrolases (picture 1).
The absolute LGL count is usually >2 × 10 9 /L, although cases with lower counts have also been described. Patients often have a history of autoimmune disease and show an indolent clinical course, and only those that experience significant and persistent cytopenias may require therapy.

Large granular lymphocyte (LGL) leukemia has been recognized by the World Health Organization classifications amongst mature T-cell and natural killer (NK) cell neoplasms. There are 3 categories: chronic T-cell leukemia and NK-cell lymphocytosis, which are similarly indolent diseases characterized by cytopenias and autoimmune conditions as opposed to aggressive NK-cell LGL leukemia. LGL is a clonal lymphoid disorder characterized by cytopenia and clonal expansion of either CD3-positive cytotoxic T lymphocytes or CD3-negative natural killer (NK) cells. Although LGL can be associated with other entities, such as AA or MDS, it is a distinct clinical entity with a specific diagnostic pathway [83,84].
