- Benign nerve sheath neoplasms of Schwann cells.
- Histologically they are distinguished in
Neurofibroma and Neurilemmoma.
- Lesions arising within the inferior alveolar canal cause fusiform enlargement of the canal with maintenance of the cortex.

- They can cause root resorption and displacement of the adjacent teeth. Adjacent teeth are vital
- Tendency for recurrence after inadequate surgery.
