Focal Fibrous Hyperplasia

  • 44% of cases of oral masses.
  • Dense collagenous tissue, with ulceration/superficial inflammation
  • Dystrophic calcification within the fibrous connective tissue stroma (often highly cellular, with 'young stellate fibroblasts'
  • No odontogenic epithelium seen.
  • Occasional strands of surface epithelium growing down into the stroma.
  • Most of these were previously diagnosed as fibromatous or ossifying epulides.
