Definition / general
  • Reactive gingival mass resembling pyogenic granuloma, which pushes teeth aside and may erode alveolar bone or involve periodontal membrane
  • Arises from periodontal ligament enclosing root of tooth
  • Central giant cell granuloma: similar to peripheral giant cell granuloma but multiloculated
Terminology
  • Also called giant cell epulis, giant cell reparative granuloma, osteoclastoma, myeloid epulis
Epidemiology
  • Usually women, 30s to 50s, although may involve children or elderly patients without teeth
Case reports

Central giant cell granuloma:
Treatment
  • Excision with curettage of base of lesion extending into adjacent periodontal membrane
  • Recurs if not completely excised or source of irritation not removed (10% recurrence rate)

  • 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
  • Variable mitotic activity
