Current Concepts in Primary Effusion Lymphoma and Other Effusion-Based Lymphomas
Primary effusion lymphoma (PEL) is a human herpes virus 8 (HHV8)-positive large B-cell neoplasm that presents as an effusion with no detectable tumor in individuals with human immunodeficiency virus infection or other immune deficiencies. PEL is an aggressive neoplasm with a poor prognosis. PEL cells show diverse morphologies, ranging from immunoblastic or plasmablastic to anaplastic. The immun...
متن کاملKSHV viral cyclin binds to p27KIP1 in primary effusion lymphomas.
Primary effusion lymphomas (PELs) represent a unique non-Hodgkin lymphoma that is consistently infected by Kaposi sarcoma herpesvirus (KSHV). PEL cells express high levels of the cell cycle inhibitor p27(KIP1) and yet proliferate actively. KSHV genome encodes a viral cyclin homolog, v-cyclin, which has previously been implicated in down-regulation of p27(KIP1) levels. To address how PEL cells c...
متن کاملAllergy and recurrent middle ear effusion
Objectives: The aim of this study was to compare the otitis media with effusion (OME) groups that improved when treated with adenoidectomy and Ventilation Tube (VT), to the group of the recurred after surgery and detect the possible role of allergy in OME. Material and Methods: This study was performed on two groups. The Patient group consisted of 38 patients with recurrent OME with allergy an...
متن کاملThere are differences in cytogenetic abnormalities among histologic subtypes of the non-Hodgkin's lymphomas.
Although many recurring chromosome abnormalities have been found in malignant lymphoma (ML) in recent years, their relationship to histology remains largely undefined. We have correlated, in the same tumor mass, chromosome findings with histology, defined by the International Working Formulation for Clinical Usage, in 120 patients. We find differences among histologies in the frequency of norma...
متن کاملCytogenetic abnormalities in a plasmacytoma.
By SEnclo MANCINELLI, JOHN R. DURANT, AND WILLIAM J. HAMMACK T SOMEWHAT CONSISTENT cytogenic changes in patients with multiple myeloma have recently been reported. Houston et al.,’ using phytohemagglutinin (PHA) stimulated peripheral blood cells, observed abnormal chromosomes in fifteen of twenty-four patients. The abnormal chromosomes were as large or larger than normal A group members with ce...
