Clonal T-cell receptor and immunoglobulin gene rearrangements are involved in the pathogenesis of angioimmunoblastic T-cell lymphoma. On gross pathology, aborization and proliferation of high endothelial venules are characteristic findings of angioimmunoblastic T-cell lymphoma. On microscopic histopathological analysis, CD4 + T-cells, CD8 + T-cells, and polyclonal plasma cells are characteristic findings of angioimmunoblastic T-cell lymphoma.
