In clinical setting, the differential diagnosis of NPC based on clinical findings would include Nasal Polyps, Non-Hodgkin Lymphoma, and Rhabdomyosarcoma.
Extranodal NK/T-cell lymphoma, nasal type (ENKTL), a distinct clinical pathological entity of non-Hodgkin's lymphoma, is closely associated with EBV infection [6], which is similar to NPC.
