title: Epidemiology and pathology of parotid tumors five-year retrospective study.
abstract: OBJECTIVE
  To retrospectively analyze the epidemiological, clinical and pathological data of parotid tumors.
  
  
  METHODS
  Reassessment of the histologic diagnosis of parotid tumor in the patients admitted to the Oral and Maxillofacial Surgery Unit of the Iasi "Sf. Spiridon" University Emergency Hospital during 2009-2013. Data on gender, age, place of residence, location, size, surgical procedure type and histopatological type were recorded.
  
  
  RESULTS
  The risk of developing pleomorphic adenonma is 7.40 times higher in women and 4.08 times higher before the age of 50 years. The risk of Warthin tumor is 16.47 times higher in male patients and 3.58 times higher in urban patients. People older than 50 years have a 7.14 times higher risk of developing malignancy and rural people have a 2.41 times higher risk of developing cancer. Diabetes, obesity and systemic hypertension were not important risk factors in our study.
  
  
  CONCLUSIONS
  According to this study age and the place of residence could be important predictors for parotid gland tumors. Since in Romania there are few epidemiological data regarding the parotid gland pathology, further cohort studies are needed for a better understanding of their clinical and pathological behavior.
