ABSTRACT
<p><b>OBJECTIVE</b>To study the clinicopathologic features and pathologic diagnosis and differential diagnosis of angioimmunoblastic T-cell lymphoma with HRS-like cells.</p><p><b>METHODS</b>Six cases of angioimmunoblastic T-cell lymphoma with HRS-like cells were examined histologically and immunohistochemically (EliVision method) and in-situ hybridization for Epstein-Barr virus-encoded RNA (EBER), and the literature was reviewed.</p><p><b>RESULTS</b>The cytologic and microscopic features of these imprints and lymph node samples showed a heterogeneous population of hematolymphoid cells, including small to intermediate lymphoid cells, immunoblasts, plasma cells, dendritic cells, and eosinophils, as well as small vessels that were surrounded by some of the abnormal cells. The neoplastic T-cells expressed CD3 and CD5 and partly positive for CD10 and bcl-6, CD21 showed expanded and irregular follicular dendritic cell (FDC) meshworks that surrounding the high HEV. The HRS-like cells were positive for MUM-1 and Ki-67, variable intensity positive for CD30, CD20, and PAX-5, but negative for CD15. EBV-positive cells included HRS-like cells and small to large-sized neoplastic T-cells, which formed small clusters or scattering in the background of the disease.</p><p><b>CONCLUSIONS</b>The clinical course of angioimmunoblastic T-cell lymphoma with HRS-like cells is aggressive. Which present with histomorphology overlap with classical Hodgkin lymphoma (CHL), similar to CHL in EBER and immunophenotype, however, it is easy to misdiagnosis as HL. Thus, angioimmunoblastic T-cell lymphoma pathology diagnosis should comprehensive analysis of different kinds of materials, including clinical features, and histological structure, and EBER, and immunophenotype, and gene rearrangement.</p>
