Plasmablastic lymphoma (PBL) is a distinct subtype of non-Hodgkin B-cell lymphoma, originally described with a strong predilection to the oral cavity of human immunodeficiency virus (HIV)-infected individuals. Data regarding patient age and gender, HIV status, initiation of and response to highly active antiretroviral therapy (HAART), tumor extent,(More)
Despite advances in HAART, patients with HIV infection remain at significantly increased risk for intermediate- and high-grade B-cell non-Hodgkin lymphoma. The reasons for this persistent risk and the clinical and molecular correlates that predict outcomes and treatment responsiveness are areas of active investigation. Here we review the epidemiologic and(More)
Whole slide imaging (WSI), or "virtual" microscopy, involves the scanning (digitization) of glass slides to produce "digital slides". WSI has been advocated for diagnostic, educational and research purposes. When used for remote frozen section diagnosis, WSI requires a thorough implementation period coupled with trained support personnel. Adoption of WSI(More)
PURPOSE Activation of the platelet-derived growth factor (PDGF) and c-kit receptors has been proposed as important in mediating the growth of AIDS-related Kaposi's sarcoma (KS). We investigated the response of KS to the PDGF receptor (PDGFR)/c-kit inhibitor, imatinib mesylate, and investigated the effect of this therapy on critical signal transduction(More)
We studied the prevalence and nature of immunoglobulin abnormalities in HIV-1-infected patients in the era of highly active antiretroviral therapy. Protein electrophoreses (PEP) were performed on and quantitative immunoglobulin levels obtained in samples from 320 consecutive HIV-1-infected patients. Samples with possible PEP abnormalities underwent(More)
Kaposi sarcoma-associated herpesvirus infection is associated with the development of 3 proliferative diseases: Kaposi sarcoma, primary effusion lymphoma, and multicentric Castleman disease. These conditions are also intimately associated with human immunodeficiency virus infection, and important synergistic interactions between these 2 viruses have been(More)
Kaposi sarcoma (KS) is a multifocal, vascular lesion of low-grade malignant potential that presents most frequently in mucocutaneous sites. KS also commonly involves lymph nodes and visceral organs. This article deals with the manifestation of KS in unusual anatomic regions. Unusual locations of KS involvement include the musculoskeletal system, central and(More)
The advent of highly active antiretroviral therapy (HAART) has lead to a substantial reduction in the prevalence, morbidity, and mortality associated with AIDS-related Kaposi's sarcoma. Similarly, concomitant advances in chemotherapy and supportive-care protocols have allowed for Kaposi's sarcoma to be managed more effectively in comparison with the(More)
