Definition / general
  • Also called giant cell epulis
  • Resembles pyogenic granuloma but may erode alveolar bone or involve periodontal membrane
  • Usually women, mean age 30 years, although may involve children or elderly patients without teeth
  • May be due to trauma, local irritation or chronic infection
  • Recurs if not completely excised
Treatment
  • Excision with curettage of base of lesion extending into adjacent periodontal membrane
Gross description
  • Inflammatory lesion up to 1.5 cm that protrudes from gingiva at site of chronic inflammation
  • Covered by gingival mucosa or ulcerated
Microscopic (histologic) description
  • Nonencapsulated aggregates of foreign body giant cells and fibroangiomatous stroma with hemorrhage, hemosiderin, acute and chronic inflammatory cells
  • Alveolar bone often expanded in edentulous patients leading to superficial bone loss with peripheral cuffing
