title: Prevalence of biopsied oral lesions in a service of oral surgery.
abstract: BACKGROUND
  A retrospective study is made of 205 case histories of patients subjected to biopsy of an oral cavity lesion.
  
  
  METHODS
  The study covered an 18-month period in which 2960 first visits were documented, including 205 oral lesions amenable to histological evaluation. Patient age and sex was evaluated, along with the clinical manifestations and location of the lesions, the biopsy technique used, the size of the tissue fragment referred for histological study, the reason for consultation (related to the lesion or otherwise), and the histological results obtained.
  
  
  RESULTS
  The most frequently biopsied lesions were cysts, including particularly root cysts (19.5%). Periapical granulomas (18.1%) and fibromas (15.7%) were also common in our series. The histological findings were varied, with a total of 35 different diagnoses. Two of the 205 biopsied oral lesions were shown to be squamous cell carcinomas (1%).
  
  
  CONCLUSIONS
  The frequency of oral lesions susceptible to histopathological study was similar to the figures reported elsewhere in the literature.
