Overview
T-PLL has the immunophenotype of a mature (post-thymic) T-lymphocyte, and the neoplastic cells are typically positive for pan-T antigens. Clonal TCR gene rearrangements for the γ and δ chains are typically found.It arises from mature (post-thymic) T-cell, which are normally involved in in cell-mediated immunity. On microscopic histopathological analysis, T-cell prolymphocytic leukemia has characteristic findings. In the peripheral blood, T-PLL consists of medium-sized lymphocytes with single nucleoli and basophilic cytoplasm with occasional blebs or projections. Different variants of T-cell lymphocytic leukemias can be differentiated based on the microscopic and gross finding.
Pathophysiology
It is postulated that the originating cell line for this disease is a mature (post-thymic) T-cell. Due to the systemic nature of this disease, leukemic cells can be found in peripheral blood, lymph nodes, bone marrow, spleen, liver, skin.
Molecular Findings
Immunophenotype
T-PLL has the immunophenotype of a mature (post-thymic) T-lymphocyte, and the neoplastic cells are typically positive for pan-T antigens CD2, CD3, and CD7 and negative for TdT and CD1a. The immunophenotype CD4+/CD8- is present in 60% of cases, the CD4+/CD8+ immunophenotype is present in 25%, and the CD4-/CD8+ immunophenotype is present in 15% of cases.
Genetic Findings
Clonal TCR gene rearrangements for the γ and δ chains are typically found. The most frequent chromosomal abnormality is the inversion of chromosome 14, specifcally inv 14(q11;q32). This is found in 80% of cases, while 10% of cases show a reciprocal translocation of chromosome 14 (t(14;14)(q11;q32)). [1]
[2] Also, abnormalities of chromosome 8 are seen approximately 75% of patients, including idic (8p11), t(8;8)(p11-12;q12), and trisomy 8. [3]
- T-cell prolymphocytic leukemia is a uncommon T- cell malignancy.
- It arises from mature (post-thymic) T-cell, which are normally involved in in cell-mediated immunity.[4]
- It is a relatively aggressive malignancy, characterized by marked lymphocytosis and involving peripheral blood, liver, spleen and bone marrow.[5]
- Factors playing role in the pathogenesis of these cells are:[6][7][8][9]
- Mutations in chromosome 14
- Mutations in chromosome 8
- Mutations in tumor suppressor gene 11q23, at the ataxia telangiectasia mutated (ATM) locus
- Inversion of chromosome 14 (14q11)
- TCR gene rearrangements for the γ and δ chains

Microscopic Pathology
- On gross pathology, characteristic findings of T-cell prolymphocytic leukemia has no remarkable finding.
- On microscopic histopathological analysis, characteristic findings of T-cell prolymphocytic leukemia include:[18]
Marrow involvement is typically diffuse with morphology similar to what is observed in peripheral blood. In the spleen, the leukemic cell infiltrate both the red pulp and white pulp, and lymph node involvement is typically diffuse through the paracortex. Skin infiltrates are seen in 20% of patients, and the infiltrates are usually dense and confined to the dermis and around the skin appendages.
In the peripheral blood, T-PLL consists of medium-sized lymphocytes with single nucleoli and basophilic cytoplasm with occasional blebs or projections. The nuclei are usually round to oval in shape, with occasional patients having cells with a more irregular nuclear outline that is similar to the cerebriform nuclear shape seen in Sézary syndrome.[19] A small cell variant comprises 20% of all T-PLL cases, and the Sézary cell-like (cerebriform) variant is seen in 5% of cases.[19]
- On microscopic histopathological analysis, characteristic findings of T-cell prolymphocytic leukemia include:[18]
- The immunophenotype CD4+/CD8- (present in 60% of cases)
- The immunophenotype CD4+/CD8+ (present in 25%)
- The immunophenotype CD4-/CD8+ (15% of cases) Different variants of T-cell Lymphocytic leukemias can be differentiated based on microscopic and gross finding.[20][21]
