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
- 22 year old woman with lesion in maxillary anterior region (Contemp Clin Dent 2012;3:S118)
- 53 year old man, 57 and 81 year old women with lesion in same location as edentulous mandible (Eur J Dent 2010;4:329)
Central giant cell granuloma:
- 15 year old girl with lesion mimicking adenomatoid odontogenic tumor (Contemp Clin Dent 2011;2:249)
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)

Gross description
- Nodular, pedunculated, 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
- Variable mitotic activity
