Large granular lymphocytic (LGL) leukemia is an uncommon disorder of mature T or natural killer (NK) cells. Most T-LGL proliferations are CD3(+)/CD8(+), although rare CD4(+) clonal T-LGL Abstract. Introduction: The purpose of this study was to analyze the data of patients with T-cell large granular lymphocyte (T-LGL) lymphocytosis associated with inflammatory arthropathy or with no arthritis symptoms. Methods: Clinical, serological as well as histopathological, immunohistochemical, and flow cytometric evaluations of 2021-03-23 The spleen and bone marrow are involved in T-LGL leukemia, although morphologic findings may be subtle. The immunophenotype is typically that of CD3+/CD8+ cytotoxic T cells. Some cases may be due LARGE GRANULAR lymphocytes (LGL) are a morphologically distinct subset of lymphocytes which constitute 10% to 15% of normal peripheral blood mononuclear cells.1 LGL include two phenotypically distinct populations of cells, T-cell LGL (T-LGL), which express the T-cell antigen CD3, and natural killer cell LGL (NK-LGL), which lack CD3 expression.2 LGL leukemias are rare but well characterized.1 T-LGL leukemia is associated with immunological abnormalities: rheumatoid factor with or without rheumatoid arthritis (RA), Coombs positive hemolytic anemia, idiopathic thrombocytopenic purpura (ITP), pure red cell aplasia (PRCA), positive anti-nuclear antibodies (ANA), anti-neutrophil cytoplasmic antibodies (ANCA), hypogammaglobulinemia, and polyclonal hypergammaglobulinemia. A proportion of 32% of T-PLL showed coexpression of CD4 and CD8. The CD4-CD8 + immunophenotype was predominant in T-LGL leukemia.

Definition T-cell large granular lymphocyte leukemia (T-LGL) exhibits a unexplained, chronic (> 6 months) elevation in large granularlymphocytes (LGLs) in the peripheral blood. It is also known by : Proliferation of large granular lymphocytes (LGLs), LGL leukemia, Tγ-lymphoproliferative disorder, T-cell chronic lymphocytic leukemia. The neoplastic cells of this disease display a mature T-cell immunophenotype, with the majority of cases showing a CD4-/CD8+ T-cell subset immunophenotype versus other permutations of those markers. [8] [9] Variable expression of CD11b , CD56 , and CD57 [10] are observed.

True T-cell chronic lymphocytic leukemia: a morphologic and immunophenotypic study of  Large granular lymphocytes (LGL) leukemias are commonly of the T-cell or NK-cell type. T-cell LGL leukemia is typically a disorder of mature CD3, CD8 and T-cell receptor TCR (TCR - T cell receptor)-αβ positive cytotoxic T-cells.

However it is more difficult to distinguish the reactive from clonal LGL population … and a plasma cell neoplasm or had a plasma cell neoplasm diagnosis followed by T-LGLL. Interestingly, in the largest case series of patients diagnosed with T-LGL and a plasma cell disorder by Sidiqi et al., all reported 22 cases, who had T-LGLs, showed the classic immunophenotype (CD8+ positive cells) [12].

The purposes of this review are to provide a concise, up-to-date summary of this uncommon, but probably underdiag-nosed, malignancy and to describe the current approach to its diagnosis and management.

The immunophenotype is that of a mature cytotoxic post-thymic T cell, but with variable aberrant features: CD3and CD8are typically expressed.

Not a single case of CD4/CD8 dual-positive T-LGLL was reported. LGLs constitute up to 15% of circulating white blood cells normally.

A proportion of 32% of T-PLL showed coexpression of CD4 and CD8. The CD4-CD8 + immunophenotype was predominant in T-LGL leukemia. Whereas tumor cells in all cases of T-PLL and primary SS showed CD5 expression, the neoplastic cells in the majority of T-LGL were dimly positive or negative for CD5. The most common immunophenotype of T-LGL leukemias (CD3+/CD8+/CD57+)6was found in 25 out of 44 patients (57%), and CD57 expression was observed in nearly 90% of cases. The CD3+/CD56+phenotype with T-LGL leukaemia is usually a clonal proliferation of suppressor T cells.
