Angioimmunoblastic T-cell lymphoma (AITL) often shows systemic symptoms related to immune dysregulation and cytokine production. Biopsy usually harbors few malignant cells in an abundant reactive background, which can be diagnostically challenging in cases with small biopsies. This study was performed to assess the value of flow cytometry (FC) and to determine the immunophenotypic alterations in 155 samples from 38 patients with AITL. FC detected an aberrant T-cell population in 97 of 155 samples that represented 0.5–90% of lymphocytes. Blood was involved in 11 of 16 patients. The most frequent immunophenotypic aberrancies included loss of CD3; altered T-cell receptor expression and aberrant CD10 expression. Altered CD3 expression was more frequently seen in peripheral blood (PB) and bone marrow (BM), whereas aberrant CD10 expression was more common in lymph node (LN). AITL cells often exhibit abnormal CD4+ immunophenotype with diminished or absent CD3 and variable CD10 expression. Multiparameter FC is an effective tool for supporting the diagnosis of AITL in any fluid and various tissue specimens types. [ABSTRACT FROM AUTHOR] |
