===Gross Pathology===
==Gross Pathology==
The normal architecture of a lymph node is partially effaced by a polymorphous infiltrate and residual follicles are commonly seen. The polymorphous infiltrate consists of lymphocytes of moderate size with pale/clear cytoplasm and smaller reactive [[lymphocytes]], [[eosinophils]], [[histiocytes]], [[plasma cells]], and [[follicular dendritic cells]]. In addition, blast-like [[B-cells]] are occasionally seen.  A classic morphological finding is the aborization and proliferation of [[high endothelial venules]].<ref name="who1"/> Hyperplastic [[germinal centers]] and [[Reed-Sternberg cells]] can also be seen.<ref name="quin1">[http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=AbstractPlus&list_uids=10524524&query_hl=30&itool=pubmed_ExternalLink]

Overview

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.
