Monoclonality and oligoclonality of T cell receptor beta gene in angioimmunoblastic T cell lymphoma.

Angioimmunoblastic T cell lymphoma (AILT) is an aggressive T cell lymphoma with an incidence of approximately 1-2% of all non-Hodgkin lymphoma. The detection of clonal T cell receptor (TCR) gene rearrangements helps in the diagnosis of T cell malignancies such as AILT, where morphological and immunohistological investigations are not always sufficient to… (More)
