Aneurysmal bone cyst
Characteristics
- It is a rare, localized, non-neoplastic, proliferative lesion of vascular tissue, containing giant cells.
- It usually occurs in young patients.
- Most common location: molar and ramus of the mandible.
- Small early lesion may be unilocular but as the lesion grows it becomes multilocular (soap bubble or honeycomb appearance).
- Often well defined and well corticated borders.
- It may cause marked bony expansion and displacement of the adjacent teeth (resorption is rare).
