Abstract
Lymphoepithelioma-like-gastric carcinoma (LEL-GC) is an Epstein-Barr virus (EBV)-associated neoplasm of the stomach reported to have a better prognosis than conventional gastric adenocarcinoma. Unlike other EBV-associated malignancies, particularly lymphoproliferative disorders and undifferentiated nasopharyngeal carcinoma, for which risk has been shown to increase in human immunodeficiency virus (HIV) infection, LEL-GC remains rare; only one HIV-infected patient with LEL-GC has been reported previously. We describe an aggressive case of EBV-associated LEL-GC in a woman co-infected with HIV 1 and hepatitis C virus. In situ hybridization of an endoscopic biopsy specimen for EBV-encoded small RNA confirmed the presence of this agent exclusively in the gastric cancer cells. Our patient had recently started antiretroviral therapy, suggesting that immune reconstitution may have been a factor in presentation of this tumour.
