[Malignant otorhinolaryngological lymphomas associated with human immunodeficiency virus infection].

Six instances of lymphoma occurring in homosexual male patients among 140 HIV-positive subjects attended at our Department of Otolaryngology were evaluated for clinical features, histopathologic features and Epstein-Barr virus (EBV) DNA. The histology of the patients was consistent with a Hodgkin's lymphoma, centroblastic lymphoma and four lymphoblastic lymphoma. High malignancy and nodal localization were characteristic of four non-Hodgkin's lymphoma, which carries a poor prognosis. The DNA in situ hybridization studies demonstrated the presence of EBV DNA sequences in the four lymphoblastic lymphoma.
