title: [Preliminary study on diagnosis of tumor like Sjögren's syndrome].
abstract: OBJECTIVE
  To explore the clinical features and diagnosis of tumor like Sjögren's Syndrome.
  
  
  METHODS
  22 cases with tumor-like Sjögren's Syndrome of parotid gland, 50 cases with pleomorphic adenoma of parotid gland and 25 cases with adenolymphoma of parotid gland were studied retrospectively.
  
  
  RESULTS
  Statistical analysis showed that tumor like Sjögren's Syndrome is predominantly in middle-aged women (40-59y) with a woman to man ratio of 6.33:1. Patients commonly present with salivary gland swelling repeatedly,varying in size,response effectively with antibiotics, accompanying dry mouth,dry eyes and aching joints. The mass probably displays medium texture and smooth appearance. The discriminant functions with tumor like Sjögren's Syndrome, pleomorphic adenoma and adenolymphoma were also established.
  
  
  CONCLUSIONS
  The discriminate functions provide a simple and practical method to diagnose tumor-like Sjögren's Syndrome.
