title: Benign fibro-osseous lesions: clinicopathologic features from 143 cases diagnosed in an oral diagnosis setting.
abstract: OBJECTIVE
  The aim of this study was to report the clinicopathologic and radiologic features of 143 benign fibro-osseous lesions (BFOLs).
  
  
  METHODS
  Clinical and radiologic information were retrieved from the patients files, and histologic features were reviewed from hematoxylin and eosin-stained histologic slides.
  
  
  RESULTS
  There were 22 ossifying fibromas (OFs), 21 fibrous dysplasias (FDs) and 100 osseous dysplasias (ODs; 65 florid, 18 focal, and 17 periapical). The mean age of the FD/OF patients was a decade lower than those with OD. The mandible was more affected than the maxilla, except in FDs. All FDs and OFs presented local swelling, whereas this was observed in <40% of the ODs. Radiologic images of the florid/periapical ODs and OFs were predominantly mixed, whereas FDs and focal ODs were predominantly radiopaque.
  
  
  CONCLUSIONS
  Florid OD, OF, and FD were the most common diagnoses, and the clinicopathologic and radiologic features were somewhat distinct from the characteristics of other populations.
