Abstract

Schwannomas are benign neoplasms arising from the sheath of myelinated nerve fibers and may occur in any part of the body. They mostly occur in the head and neck region, accounting for about 25% to 45% of all cases. The eighth cranial nerve is the most common site of origin. About 4% of all head and neck schwannomas originate in the nasal cavity and paranasal sinuses. The best treatment of schwannomas is surgical excision. Since it is an encapsulated tumor, difficultly is rarely encountered in its complete removal, and recurrence is unlikely. We present a unique and rare case of a 71-year-old man with a recurrent septal mass, finally diagnosed as a schwannoma, with a review of the literature.

Figure

  • Fig. 1. These photos show about 1.5×1.2 cm sized mass on left side of nasal septum. A: Basal view. B: Endoscopic finding.

  • Fig. 2. The PNS CT and Brain MRI findings. These show about 1.5×1.2 cm sized non-enhanced mass in caudal septum. A: Enhanced axial view. B: Enhanced coronal view. C: The mass shows intermediate signal intensity in T1 weighted image. D: T2 Fat-saturation image shows the mass with high signal intensity.

  • Fig. 3. Pathologic findings. A: Gross photo shows two well-circumscribed masses. One is about 1.8×1.3 cm sized and the other is 1.0×0.8 cm sized. B: The tumor is well circumscribed (H&E, ×40). C: This shows characteristic nuclear palisading (Verocay bodies) (H&E, ×200). D: The tumor cells are immunoreactive for S-100 protein (S-100, ×200).
