title: [Clinical analysis on 18 cases of primary nasal cavity and sinuses T/NK lymphomas].
abstract: OBJECTIVE
  To investigate the clinical characteristics and treatment effect of primary sinonasal T/NK lymphomas.
  
  
  METHODS
  Eighteen cases of primary sinonasal T/NK lymphomas were reviewed retrospectively. The clinical behavior, clinical diagnostic characteristics and prognosis were studied.
  
  
  RESULTS
  The clinical symptoms of these patients included nasal obstruction, epistaxis, nasal discharge, intumescence, ulcer and fever so on. Clinical diagnosis was easy to be misdiagnosed. The prognosis of patients that higher stage and higher malignant were bad.
  
  
  CONCLUSIONS
  Sinonasal T/NK lymphomas are a distinct clinicopathological category and the clinical symptoms are nonspecificness. We should pay attention to distinction and avoiding misdiagnosis. The prognosis is relative to pathological category and clinical stage.
