Benign tumors of neural origin .
- Benign neoplasms originating from peripheral nerves or Schwann cells.
Histologically, they are distinguished into neurofibromas and neurilemmomas (or schwannomas). - Lesions that develop in the inferior alveolar nerve canal cause widening of the canal as they expand the cortical walls of it.
- Most common symptoms are pain and swelling.
- Usually unilocular radiolucency with well-defined borders (cyst-like radiolucency).
- The adjacent teeth are vital and root displacement or resorption may be apparent.
- They have the tendency for recurrence after inadequate surgery.
