title: [Multifocal nodular oncocytosis hyperplasia of the parotid gland].
abstract: OBJECTIVE
  Oncocytic lesions rarely affect the parotid gland, accounting for less than 1% of all salivary lesions. The WHO classification described three main types: diffuse oncocytosis, focal nodular oncocytosis hyperplasia, and oncocytoma. Multifocal nodular oncocytosis hyperplasia of the parotid gland represents an extremely rare, non-tumorous pathology of the parotid gland.
  
  
  METHODS
  We report a case of multifocal nodular oncocytosis hyperplasia of the parotid gland in a 70-year-old woman who was referred for a left preauricular mass that had gradually increased in size over the last 2 years. No lymph node of the neck was palpable.
  
  
  RESULTS
  MRI demonstrated multiple bilateral lesions of the parotid glands. Total parotidectomy, preserving the facial nerve, was performed.
  
  
  CONCLUSIONS
  We discuss the physiopathology and the treatment of multifocal nodular oncocytosis hyperplasia and provide a review of the literature.
