Plasmablastic Lymphoma of the Small Intestine in an HIV- And EBV-negative Patient

Abstract

Plasmablastic lymphoma (PBL) is a rare aggressive B-cell lymphoproliferative disorder that is strongly associated with immunodeficiency, most often with human immunodeficiency virus (HIV) and Epstein-Barr virus (EBV) infection, and that mainly occurs in the oral cavity. Although some clinical features can lead to a diagnosis, PBL in an extraoral site is difficult to suspect clinically in a patient who is HIV negative. The small intestine as a site of PBL has also been described very rarely. We herein present a rare case of PBL of the small intestine in an 85-year-old HIV- and EBV-negative male.
