Summary
Peripheral T-cell and NK-cell lymphomas are rare but aggressive cancers. This review details key features of nasal NK/T cell lymphoma, enteropathy-type intestinal T-cell lymphoma, and angioimmunoblastic T-cell lymphoma.
Area of Science:
- Hematology
- Oncology
- Immunology
Context:
- Peripheral T-cell and Natural Killer (NK)-cell lymphomas are uncommon malignancies in Europe, representing less than 10% of all malignant lymphomas.
- These rare lymphomas encompass several distinct entities with unique clinical and pathological features.
Purpose:
- This review aims to present the salient features of frequently occurring T-cell and NK-cell lymphomas.
- To provide an overview of nasal NK/T cell lymphoma, enteropathy-type intestinal T-cell lymphoma, and angioimmunoblastic T-cell lymphoma.
Summary:
- Nasal NK/T cell lymphoma, often angiocentric, expresses CD56, CD2, and EBER, frequently derived from NK cells.
- Enteropathy-type intestinal T-cell lymphoma, associated with celiac disease, has a poor prognosis and exhibits specific immunophenotypic markers.
- Angioimmunoblastic T-cell lymphoma is characterized by specific morphology and clinical signs of immune dysregulation.
Impact:
- Enhances understanding of rare T-cell and NK-cell lymphomas for improved diagnosis and treatment strategies.
- Highlights the diagnostic criteria and clinical behavior of specific lymphoma subtypes, aiding clinicians in patient management.
- Contributes to the classification and characterization of lymphoid neoplasms, advancing the field of hematologic oncology.
