ABSTRACT
<p><b>OBJECTIVE</b>To investigate the differences between primary mediastinal B-cell lymphoma (PMBCL) and non-mediastinal conventional diffuse large B-cell common lymphoma (DLBCL) in immunoglobulin gene rearrangement and EB virus infections.</p><p><b>METHODS</b>Twenty cases of PMBCL and 30 cases of non-mediastinal DLBCL were collected from September, 2000 to May, 2011. Pathological data were retrospectively analysed. Immunoglobulin heavy chain and light chain gene rearrangements and EBER in-situ hybridization were performed.</p><p><b>RESULTS</b>Six of 20 cases of PMBCL showed monoclonal gene rearrangement, all of which were weakly detected. Twenty-seven of 30 cases of ordinary diffuse large B-cell lymphoma showed monoclonal gene rearrangement, which were strongly detected (90.0%). Only 1 of 20 cases PMBCL and 2 of 30 cases of DLBCL were positive for EBER in-situ hybridization.</p><p><b>CONCLUSIONS</b>The detection rate of immunoglobulin gene rearrangement is significantly lower in PMBCL than that of non-mediastinal DLBCL. However, EB virus infection rates are very low in both types of lymphomas.</p>
