Primary lymphomatous effusions are represented by cases of non-Hodgkin's lymphoma (NHL) which grow in liquid phase in the serous body cavities in the absence of solid tumour masses. Based on morphologic, immunophenotypic, virologic and genotypic features, primary lymphomatous effusions are distinguished into body cavity-based lymphoma (BCBL), Burkitt's lymphoma (BL) and immunoblastic large-cell lymphoma. The histogenesis and pathogenesis of primary lymphomatous effusions are virtually unclarified. In this study, we have established 2 cell lines (CRO-AP/1 and CRO-AP/2) representative of 2 distinct categories of primary lymphomatous effusion, BCBL (CRO-AP/2) and BL (CRO-AP/1). Both CRO-AP/1 and CRO-AP/2 carry monoclonal re-arrangements of the immunoglobulin genes which are identical to those of the respective parental tumours. Consistent with its BCBL origin, CRO-AP/2 is characterised by a non-B, non-T phenotype and harbours infection by HHV-8 (approx. 100 viral copies/cell) and Epstein-Barr virus. Conversely, CRO-AP/1 expresses several B cell-associated antigens, lacks HHV-8 infection and carries the genetic hallmark of BL, i.e., a chromosomal breakpoint of band 8q24. CRO-AP/1 and CRO-AP/2 may be valuable for the biologic characterization of primary lymphomatous effusions, particularly since the number of available cell lines derived from such lymphomatous effusions is extremely limited.

D010996 Pleural Effusion Presence of fluid in the pleural cavity resulting from excessive transudation or exudation from the pleural surfaces. It is a sign of disease and not a diagnosis in itself. Effusion, Pleural,Effusions, Pleural,Pleural Effusions
D002051 Burkitt Lymphoma A form of undifferentiated malignant LYMPHOMA usually found in central Africa, but also reported in other parts of the world. It is commonly manifested as a large osteolytic lesion in the jaw or as an abdominal mass. B-cell antigens are expressed on the immature cells that make up the tumor in virtually all cases of Burkitt lymphoma. The Epstein-Barr virus (HERPESVIRUS 4, HUMAN) has been isolated from Burkitt lymphoma cases in Africa and it is implicated as the causative agent in these cases; however, most non-African cases are EBV-negative.

D016130 Immunophenotyping Process of classifying cells of the immune system based on structural and functional differences.

D016483 Lymphoma, AIDS-Related B-cell lymphoid tumors that occur in association with AIDS. Patients often present with an advanced stage of disease and highly malignant subtypes including BURKITT LYMPHOMA; IMMUNOBLASTIC LARGE-CELL LYMPHOMA; PRIMARY EFFUSION LYMPHOMA; and DIFFUSE, LARGE B-CELL, LYMPHOMA. The tumors are often disseminated in unusual extranodal sites and chromosomal abnormalities are frequently present. It is likely that polyclonal B-cell lymphoproliferation in AIDS is a complex result of EBV infection, HIV antigenic stimulation, and T-cell-dependent HIV activation.
