Abstract
Neurilemmoma is a benign neoplasm believed to arise from the Schwann's sheath. Neurilemmoma of the oral region is an uncommon disease and especially that of the cheek is very rare.
We reported a case of large neurilemmoma occurring in the area from the cheek to the pterygopalatine fossa in a 75-year-old woman, complaining a swelling of the cheek. The tumor was removed en bloc by intraoral approach. It was spherical in shape, measuring about 35×25×15mm and included a large cyst. Histopathological findings showed features of neurilemmoma (type A and B of Antoni's pathological classification).
We reviewed Japanese literature of neurilemmoma occurring in the region from the cheek to the infratemporal fossa reproted from 1970 to 1988 and 13 cases were found.
