Neurilemmoma Originating from the Hypoglossal Nerve in the Floor of the Mouth

growing and encapsulated tumour originating from Schwann cells (1-4). Approximately 25% to 40% of all neurilemmomas are seen in the head and neck region, and only 1% exhibit an intraoral localisation (5,6). Neurilemmomas of the hypoglossal nerve (XIIth cranial nerve) are uncommon, mostly originating from the intracranial portion or having a dumb-bell shape with intracranial and extracranial components (7,8). Neurilemmomas of the most peripheral segment of the hypoglossal nerve, in the lower oral cavity, are very rare.
