Abstract
A link between Epstein-Barr Virus (EBV) infection, systemic lupus erythematosus (SLE) and non-Hodgkin's lymphoma (NHL) has been recently reported in literature. Here we report a case of diffuse large B-cell lymphoma (DLBCL) with a particularly aggressive clinical course in an SLE patient with EBV infection. A 49-year-old woman with a long history of SLE was admitted to the Department of Experimental and Clinical Medicine and dramatically died a few hours later. The autopsy described no evidence of active lymphoproliferative disorder. Instead, histological examination demonstrated an atypical lymphocitic proliferation in lymph node, kidneys, pericardium and uterus. Immunoistochemically, the lymphomatous cells were positive with CD19, CD20, CD22 and CD79a, which was consistent with a DLBCL. The cells were also reactive to EBV markers, indicating the possible role of previous EBV infection in DLBCL pathogenesis.
