Large granular lymphocytic leukemia is a disease that exhibits an unexplained, chronic (> 6 months) elevation in large granular lymphocytes (LGLs) in the peripheral blood.[1]
It is sometimes known as T-cell large granular lymphocyte leukemia (specifying involvement of the T cells). However, NK large granular lymphocyte leukemia (involving natural killer cells) is also possible.[2]
It is also known by the following terms: proliferation of large granular lymphocytes (LGLs), LGL leukemia, Tγ-lymphoproliferative disorder, and, in common with other T cell leukemias such as T-cell prolymphocytic leukemia, T-cell chronic lymphocytic leukemia.[1]

Epidemiology[edit]
T-LGL is a rare form of leukemia, comprising 2-3% of all cases of small lymphocytic leukemias.[1]
Etiology[edit]
The postulated cells of origin are a transformed CD8+ T-cell with clonal rearrangements of β chain T-cell receptor genes for the majority of cases and a CD8- T-cell with clonal rearrangements of γ chain T-cell receptor genes for a minority of cases.[1]
Clinical features[edit]
Clinical presentation[edit]
This disease is known for an indolent clinical course and incidental discovery.[1] The most common physical finding is moderate splenomegaly. B symptoms are seen in a third of cases, and recurrent infections due to the associated neutropenia are seen in almost half of cases.[3][4][5][6]
Rheumatoid arthritis is commonly observed in patients with T-LGL, leading to a clinical presentation similar to Felty's syndrome.[7] Signs and symptoms of anemia are commonly found, due to the association between T-LGL and erythroid hypoplasia.[8]
Laboratory findings[edit]
The requisite lymphocytosis of this disease is typically 2-20x109/L.[8]
Immunoglobulin derangements including hypergammaglobulinemia, autoantibodies, and circulating immune complexes are commonly seen.[6][9][10][11]
Sites of involvement[edit]
The leukemic cells of T-LGL can be found in peripheral blood, bone marrow, spleen, and liver. Nodal involvement is rare.[1][3]
Prognosis[edit]
The 5 year survival has been noted as 89% in at least one study from France of 201 patients with T-LGL leukemia.[12]
Morphology[edit]
Peripheral blood[edit]
The neoplastic lymphocytes seen in this disease are large in size with azurophilic granules that contains proteins involved in cell lysis such as perforin and granzyme B.[13]
Bone marrow[edit]
Bone marrow involvement in this disease is often present, but to a variable extent. The lymphocytic infiltrate is usually interstitial, but a nodular pattern rarely occurs.[1]
Molecular Findings[edit]
Immunophenotype[edit]
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.[4][5] Variable expression of CD11b, CD56, and CD57[6] are observed. Immunohistochemistry for perforin, TIA-1, and granzyme B are usually positive.[1]
| Type |
Immunophenotype |
| Common type (80% of cases) |
CD3+, TCRαβ+, CD4-, CD8+ |
| Rare variants |
CD3+, TCRαβ+, CD4+, CD8- |
| CD3+, TCRαβ+, CD4+, CD8+ |
| CD3+, TCRγδ+, CD4 and CD8 variable |
Genetic findings[edit]
Clonal rearrangements of the T-cell receptor (TCR) genes are a necessary condition for the diagnosis of this disease. The gene for the β chain of the TCR is found to be rearranged more often than the γ chain. of the TCR.[10][14]
Treatment[edit]
Alemtuzumab has been investigated for use in treatment of refractory T-cell large granular lymphocytic leukemia.[15]
