title: [A clinico-pathological study of 20 cases of Warthin's tumors of the parotid gland].
abstract: OBJECTIVE
  The purpose of this study was to clarify the clinico-pathological findings of Warthin's tumors.
  
  
  METHODS
  Twenty cases of Warthin's tumors treated at our clinic during the past 22 years and their medical charts and imaging films were reviewed.
  
  
  RESULTS
  Warthin's tumors occurred more frequently in middle-aged or elderly men than in women. Solitary tumors were significantly larger (p < 0.05) than multiple tumors. Warthin's tumors that accumulated 99mTc were significantly larger (p < 0.05) than those that did not. In addition, there was no difference in clinical findings between the two histopathologic types of Warthin's tumors.
  
  
  CONCLUSIONS
  The frequent occurrence of multiple Warthin's tumors indicated the importance of an accurate clinical and radiological examination of parotid glands, in order to detect possible multiple lesions prior to treatment.
