Angioimmunoblastic T-cell lymphoma
The lymphoma cell is a peripheral T lymphocyte in various stages of differentiation. The neoplastic clone expresses T-cell antigens and is usually CD4+. The malignant T-cells are believed to secrete cytokines responsible for the polyclonal B-cell hyperplasia observed in involved nodes. Clonality studies demonstrated a monoclonal rearrangement of the bchain of the T-cell receptor (TCR) in the ma...
متن کاملDetection of the G17V RHOA Mutation in Angioimmunoblastic T-Cell Lymphoma and Related Lymphomas Using Quantitative Allele-Specific PCR
Angioimmunoblastic T-cell lymphoma (AITL) and peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) are subtypes of T-cell lymphoma. Due to low tumor cell content and substantial reactive cell infiltration, these lymphomas are sometimes mistaken for other types of lymphomas or even non-neoplastic diseases. In addition, a significant proportion of PTCL-NOS cases reportedly exhibit featu...
متن کاملAngioimmunoblastic T cell lymphoma: novel molecular insights by mutation profiling
Angioimmunoblastic T cell lymphoma (AITL) originates from follicular helper T-cells and is characterised by a polymorphic infiltrate with the neoplastic T-cells forming small clusters around the follicle and high endothelial venules. Despite the recent advances in its phenotypic characterisation, the genetics and molecular mechanisms underlying AITL are not fully understood. In the present stud...
متن کاملAngioimmunoblastic T-cell lymphoma management.
Angioimmunoblastic T-cell lymphoma (AITL) is a frequent subtype of peripheral T-cell lymphoma (PTCL) that is clinically characterized by generalized lymphadenopathy, extranodal involvement, advanced stage at presentation, hypergammaglobulinemia, and significant immune dysregulation resulting in infections as the most common cause of death. Recent advances in pathobiology of AITL have improved o...
متن کاملConjunctival Angioimmunoblastic T-Cell Lymphoma.
Angioimmunoblastic T-cell lymphoma (AITL) represents an uncommon variant of T-cell lymphomas and most often presents insidiously with systemic symptoms. This report constitutes the first documented case of conjunctival AITL, masquerading as nodular episcleritis, and describes both the clinical and pathological findings. Furthermore, conjunctival T-cell lymphoma in general remains a rare occurre...
