Benign tumors of neural origin


  • 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.
  • Most common symptoms are pain and swelling.
  • More often are unilocular with well-defined margin (cyst-like radiolucency).
  • They can cause root resorption and displacement of the adjacent teeth. Adjacent teeth are vital
  • Tendency for recurrence after inadequate surgery.
