A Schwannoma is an encapsulated and solitary tumor of the Schwann's sheath of the nerve, arising in the cranial, sympathetic or peripheral nerves. Benign tumors of the pharynx are rare, but among the benign tumors which occur in the pharynx, Schwannoma appears to be more common. About 25% of all Schwannomas occur in the head and neck area. The authors recently observed a huge Schwannoma, 9×6×5 cm in size and 153 gm in weight, which originated from the glossopharyngeal nerve. The patient was a 33 year old housewife who complained of a fist-sized mass on the left side of the fauces and had a history of incomplete resection about 2 years ago. The tumor which originated from the trunk of the glossopharyngeal nerve was removed after admission to our hospital. The pathological findings revealed Schwannoma.
