Core Tip
Core tip: Plasmablastic lymphoma (PBL) is a rare form of non-Hodgkin’s lymphoma that is associated with human immunodeficiency virus (HIV) infection. Although PBL is most commonly observed in the oral cavity of HIV-positive patients, it can also be observed at extra-oral sites in HIV-negative patients with an underlying immunosuppressive state. The gastrointestinal tract and skin are the most commonly involved extra-oral organ systems and cases of PBL in the colon are unusual. We report a case of HIV-negative PBL that occurred in the sigmoid colon.
