title: Sclerosing polycystic adenosis of the parotid gland: diagnosis and management.
abstract: OBJECTIVE
  To describe diagnostic and therapeutic management of a rare parotid lesion: sclerosing polycystic adenosis.
  
  
  METHODS
  We report a case of persistent right intraparotid tumefaction.
  
  
  RESULTS
  A 68-year-old man was referred with a right parotid nodule of 2 years' evolution. Cytology diagnosed pleomorphic adenoma, verified on MRI. Conservative subtotal parotidectomy diagnosed sclerosing polycystic adenosis. Over 1 year's regular follow-up, there were no signs of local recurrence.
  
  
  CONCLUSIONS
  Sclerosing polycystic adenosis of the parotid gland is a rare and recently described entity presenting several analogies to the much more frequent cystic mastitis. Although benign and well-delimited, it requires complete exeresis of the parotid, due to a non-negligible risk of recurrence.
