title: Induction of parotitis by fine-needle aspiration in parotid Warthin's tumor.
abstract: OBJECTIVE
  To estimate parotitis caused by fine-needle aspiration (FNA) in parotid Warthin tumor.
  
  
  METHODS
  Case series with chart review.
  
  
  METHODS
  Hospital records were reviewed for 104 parotid tumors (103 patients) including 35 Warthin tumors, which underwent FNA within our department.
  
  
  RESULTS
  Three patients with four Warthin tumors among them noticed parotid pain, swelling, and abscess formation as a consequence of acute parotitis after FNA. Examinations of the materials obtained from tumor puncture or drainage before the start of antibiotic therapy showed no bacterial association in any patient. Two of the patients with Warthin tumor underwent parotidectomy, and the surgical specimens indicated histopathological changes with necrosis, abscess, granuloma, and the infiltration of inflammatory cells including Langhans-type multinucleated giant cells.
  
  
  CONCLUSIONS
  It is conceivable that Warthin tumor bears the characteristics of inflammation induced by the FNA procedure without any relation to infection. Therefore, it may be better to avoid routine FNA and give priority to diagnostic imagings over FNA in the diagnosis of tumors strongly suspected as Warthin tumor.
