CD56 Negative Extranodal NK/T-cell Lymphoma of the Orbit Mimicking Orbital Cellulitis

Abstract

The authors demonstrate how the acute presentation of an aggressive extranodal NK/T-cell lymphoma can present in a similar fashion as orbital cellulitis. Additionally, the case highlights that a unilateral pansinusitis with involvement of the skull base and orbit is likely due an aggressive malignant process in an immune competent patient.
