title: [Nasal NK/T cell lymphoma with outstanding performance of ocular symptoms].
abstract: OBJECTIVE
  To investigate the clinical features and misdiagnosis of nasal NK/T cell lymphoma with outstanding performance in ocular symptoms.
  
  
  METHODS
  Clinical data of 11 patients who had nasal NK/T cell lymphoma with the outstanding performances in ocular symptoms during 2009 to 2011 were retrospectively analyzed.
  
  
  RESULTS
  The rate of misdiagnosis in the first diagnosis and first pathological diagnosis were 72.7% and 27.3% respectively. Nasal NK/T cell lymphoma with obvious ocular symptoms developed quickly and had almost special imaging findings.
  
  
  CONCLUSIONS
  Nasal NK/T cell lymphoma with outstanding performance of ocular symptoms can be easily misdiagnosed. Comprehensive consideration of the clinical features, imaging findings and pathological examination do help to make accurate diagnosis early.
