title: Oncocytoma of the Deep Lobe of the Parotid Gland.
abstract: BACKGROUND
  Oncocytoma or oxyphilic adenoma is uncommon salivary gland tumour, occurs predominantly in the in patients older than 60 years of age. Clinically oncocytoma resemble other salivary tumours while histology is typically consisting of oncocytes with many hyperplastic mitochondria. It usually occurs in the parotid gland. Because the features of oncocytoma are similar to those of other benign and low-grade malignant salivary tumours, clinical diagnosis is often challenging.
  
  
  METHODS
  This report presents the pathologic and imaging findings of an oncocytoma arising in the deep lobe of the right parotid gland in a 74-year-old male. Oncocytoma was diagnosed on the basis of histological, magnetic resonance imaging (MRI), scintigraphic findings and fine needle aspiration cytology (FNAC).
  
  
  CONCLUSIONS
  This case was unique because in the literature there are few articles about the rare presentation and deep lobe location of this type of parotid oncocytoma.
