- It is lined by keratinizing epithelium.
- It is usually located in the mandible (posterior body and ramus region).
- It can occur at any age but most develop during the second and third decade.
- It can become very large. It extends along the body of the mandible causing minimal mediolateral expansion.
- Unilocular (often with scalloped margins) or multilocular (more often in larger lesions).
- Smooth margins, well-defined, often well-corticated.
- Tendency for recurrence after inadequate surgery.
- Adjacent teeth: vital, rarely resorbed.

- Ameloblastoma (multilocular)
- Aneurysmal bone cyst
- Giant cell granuloma, central (multilocular)
- Odontogenic myxoma
