title: Nasal NK/T cell lymphoma mimicking an latrogenic lateral nasal wall infection: a diagnostic dilemma.
abstract: Extra nodal NK/T cell lymphoma, 'nasal type' is a rare clinicopathological entity. The prevalence of nasal lymphoma is estimated at 0.17-1.5% for all non -Hodgkin's lymphomas (NHL), of which 45% originate from the NK/T cell. It is more commonly encountered in Asian countries. The main clinical features are nasal congestion and epistaxis due to local aggressive destruction. It has a distinct immunophenotypic profile of CD2+, CD56+ and CD3-. The tumor often shows polymorphic lymphoreticular infiltrates and necrosis. We present a case of a 50-year-old male who presented with lateral nasal wall infection following endoscopic sinonasal surgery and later proven to be extranodal NK/T cell 'nasal type' lymphoma with immunophenotypic features.
