title: Epstein-Barr virus in a CD8-positive T-cell lymphoma.
abstract: In contrast to its role in B-lymphomagenesis, Epstein-Barr Virus (EBV) only incidentally has been associated with T-cell lymphomas. In the present report we describe a fourth patient with EBV-related T-cell lymphoma. The patient presented with an angio-immunoblastic lymphadenopathy (AILD)-like T-cell lymphoma. Serology was compatible with chronic Epstein-Barr (EBV) infection. After a 1-year period of waxing and waning lymphadenopathy, this lymphoma evolved to an aggressive CD8+ Immunoblastic T-cell lymphoma. A relationship with the chronic EBV infection was indicated by the finding of EBV genome in the tumor tissue by Southern blot analysis. Moreover, EBV nuclear antigen (EBNA) was detected in situ within individually defined CD8+ tumor cells by two-color immunofluorescence. Two alternative possibilities, namely that EBV primarily played a role in lymphomagenesis of the AILD-like T-cell lymphoma or that the virus was an additional oncogenic event in the final process of tumor progression to the immunoblastic lymphoma, are discussed.
