Ancient schwannoma of the facial nerve: a case report.

Author information

Department of Surgical Sciences, Organ Transplantations and Advanced Technologies University of Catania.


Ancient schwannomas are rare benign tumours, deriving from neural crest cells. Schwannomas of the head and neck are frequently misdiagnosed and preoperative investigations are often fruitless. We report a very rare case of a patient with a schwannoma of the seventh nerve. T.A., a 43-year-old male, was referred to our department in September 2003 with a 6-month history of a gradually enlarging asymptomatic right neck mass. Ultrasonography of the parotid gland demonstrated the presence of a nodule, with irregular borders, measuring about 2.90 x 2.00 x 1.70 cm. During surgery we found a mass apparently spreading from the parotid gland and therefore we decided to resect the mass together with the gland. The histological examination yielded a diagnosis of ancient schwannoma. Schwannomas are very rare and approximately 25-30% of all reported cases occur in the head and neck, mostly in the eighth nerve, while involvement of the seventh nerve is extremely rare.
