Angioimmunoblastic T-cell lymphoma is a rare non-Hodgkin lymphoma with dismal prognosis. The median age of presentation ranges from 62 to 69 years with generalized lymphadenopathy, B symptoms, and hepatosplenomegaly as the most prevalent symptoms. The combination of B-cell and T-cell proliferations is common in AITL and the B-cell component may resemble Reed-Sternberg-like B-cells. Epstein-Barr virus is estimated to be present in 80–95% of AITL biopsies. Only a handful of EBV-negative AITL cases with EBV-negative RS-like B-cells have been reported over the last decade. We present a rare case of EBV-negative AITL with chylous ascites and chylothorax. Microscopic and immunohistochemical analysis revealed the presence of EBV-negative Reed-Sternberg-like B-cells in the tumor.

Angioimmunoblastic lymphadenopathy with dysproteinemia (AILD) is a peculiar T cell lymphoma, as expanding B cell clones are often present besides the malignant T cell clones. In addition, large numbers of Epstein-Barr virus (EBV)-infected B cells are frequently observed. To analyze the differentiation status and clonal composition of EBV-harboring B cells in AILD, single EBV-infected cells were micromanipulated from lymph nodes of six patients with frequent EBV+ cells and their rearranged immunoglobulin (Ig) genes analyzed. Most EBV-infected B cells carried mutated Ig genes, indicating that in AILD, EBV preferentially resides in memory and/or germinal center B cells. EBV+ B cell clones observed in all six cases ranged from small polyclonal to large monoclonal expansions and often showed ongoing somatic hypermutation while EBV− B cells showed little tendency for clonal expansion. Surprisingly, many members of expanding B cell clones had acquired destructive mutations in originally functional V gene rearrangements and showed an unfavorable high load of replacement mutations in the framework regions, indicating that they accumulated mutations over repeated rounds of mutation and division while not being selected through their antigen receptor. This sustained selection-free accumulation of somatic mutations is unique to AILD. Moreover, the survival and clonal expansion of “forbidden” (i.e., Ig-deficient) B cells has not been observed before in vivo and thus represents a novel type of viral latency in the B cell compartment. It is likely the interplay between the microenvironment in AILD lymph nodes and the viral transformation that leads to the survival and clonal expansion of Ig-less B cells.

Abstract Patients with angioimmunoblastic T-cell lymphoma can have profound immune dysfunction and immunodeficiency. Epstein-Barr virus–driven B-cell lymphoid proliferation can occur in angioimmunoblastic T-cell lymphoma, as in other immunodeficiency states. However, few cases of Epstein-Barr virus–positive B-cell lymphoma arising in patients with preexisting angioimmunoblastic T-cell lymphoma have been reported. We report a case of angioimmunoblastic T-cell lymphoma in which diffuse large B-cell lymphoma developed 56 months after the diagnosis of angioimmunoblastic T-cell lymphoma. The patient survived for 9 years after the initial diagnosis of angioimmunoblastic T-cell lymphoma, and molecular studies performed on multiple biopsy specimens during this period revealed the dynamic nature of clonal lymphoid expansion. Epstein-Barr virus latent membrane protein 1 and Epstein-Barr virus– encoded RNA were detected in the diffuse large B-cell lymphoma, suggesting that Epstein-Barr virus may have played a role in the pathogenesis of the diffuse large B-cell lymphoma.
