title: Synchronous bilateral acinic cell carcinoma of the parotid: when a tumor reveals another one.
abstract: BACKGROUND
  Acinic cell carcinoma is a rare form (2-4%) of parotid tumor. It is, however, the most frequent form of bilateral parotid tumor and the second most frequent form in children.
  
  
  METHODS
  A 22-year-old man had several years' history of left parotid tumor, discovered to be acinic cell carcinoma. MRI found a synchronous contralateral tumor of the same histologic nature.
  
  
  CONCLUSIONS
  This case highlights the need for rigorous examination of the contralateral parotid in case of parotid tumor and especially of acinic cell carcinoma.
