NKTCL is a rare and destructive midline tumor that can be easily misdiagnosed as other more common inflammatory processes. The differential diagnosis of NKTCL should always be kept in mind for any lesion of the paranasal sinuses with atypical presentation and nonresponsive to conventional treatments.
Keywords: NKTCL lymphoma; fungal sinusitis; midline lethal granuloma; periorbital cellulitis.
