Plasmablastic Lymphoma of the Maxillary Sinus Causing Orbital Complication

Abstract

Plasmablastic lymphoma (PBL) is a rarely seen diffuse large B cell lymphoma variant associated with acquired immunodeficiency syndrome, oral mucosa localization, and a poor prognosis. There is not yet a standard protocol for the treatment of PBL; the treatment of a small number of human immunodeficiency virus (HIV)-negative cases has been reported in case reports and series and shared on a case-by-case basis. Presently described is the case of a 60-year-old man with PBL that originated in the sinus and spread to the orbit. The patient was HIV-negative and immunocompetent. The treatment and follow-up are presented in the context of the available literature.
