Primary effusion lymphoma containing human herpesvirus 8 DNA in two AIDS patients with Kaposi's sarcoma.
BACKGROUND AND OBJECTIVE Primary effusion lymphomas (PELs) containing Kaposi's sarcoma-associated herpesvirus (human herpesvirus 8/HHV-8) DNA sequences represent a distinct but heterogeneous group of rare non-Hodgkin's lymphomas of null-cell phenotype/B-cell origin. We aimed to describe the clinicopathologic features of two human immunodeficiency virus (HIV)-related PELs occurring in homosexual...
متن کاملPrimary effusion lymphoma.
Primary effusion lymphoma (PEL) is a rare HIV-associated non-Hodgkin's lymphoma (NHL) that accounts for approximately 4% of all HIV-associated NHL. PEL has a unique clinical presentation in having a predilection for arising in body cavities such as the pleural space, pericardium, and peritoneum. PEL cells are morphologically variable with a null lymphocyte immunophenotype and evidence of human ...
متن کاملKaposi's sarcoma-associated herpesvirus (KSHV or HHV8) in primary effusion lymphoma: ultrastructural demonstration of herpesvirus in lymphoma cells.
Recent molecular evidence suggests an association with a new herpesvirus, Kaposi's sarcoma-associated herpesvirus (KSHV/HHV-8), and primary effusion lymphomas (PELs). PELs have a characteristic morphology, phenotype, and clinical presentation, with malignant effusions in the absence of a contiguous solid tumor mass. We have established a cell line (KS-1) from a KSHV-positive human immunodeficie...
متن کاملExpression profile of human herpesvirus 8 (HHV-8) in pyothorax associated lymphoma and in effusion lymphoma.
AIMS Pyothorax associated lymphoma (PAL) occurs in a clinical setting of longstanding pyothorax or chronic inflammation of the pleura. Like primary effusion lymphoma, it has an association with Epstein-Barr virus (EBV), and is confined to the pleural cavity, but has differing morphological and phenotypic features. Human herpesvirus 8 (HHV-8) has been consistently reported in primary effusion ly...
متن کاملTranscription pattern of human herpesvirus 8 open reading frame K3 in primary effusion lymphoma and Kaposi's sarcoma.
Human herpesvirus 8 (HHV-8) is found in immunoblastic B cells of patients with multicentric Castleman's disease (MCD) and, predominantly in a latent form, in primary effusion lymphoma (PEL) cells and Kaposi's sarcoma (KS) spindle cells. Recent studies have shown that upon reactivation, HHV-8 expresses factors that downregulate major histocompatibility class I proteins and coactivation molecules...
