Malignant schwannoma is a rare lesion which develops at the level of the peripheral nervous system sheath. Its cervico-facial localisation is very scarce, and its diagnosis is difficult to establish in spite of a complete radiological examination; definitive diagnosis depends on the histological examination. There is no strict consensus for the management of these lesions, however a wide surgical excision and neck dissection associated with or without postoperative radiotherapy and/or chemotherapy are the gold standard methods of treatment. The prognosis is usually bad due to the high risk of recurrence, sometimes difficult to diagnose.
