Endoscopic excision of nasal septal schwannoma:case report and review of literature

Abstract

Schwannomas are benign tumors arising from Schwann cells of myelinated nerve sheath. Schwannomas of the nasal cavity and paranasal sinuses are rare, with only 4% occurrence. We report a case of a 48-year-old lady who presented with 1-year history of progressively worsening left nasal blockage. Rigid nasoendoscopy showed a smooth, globular mass occupying the left nasal cavity. The mass arose from the left nasal septum and impinged on the anterior part of the middle turbinate posteriorly and inferior turbinate anteriorly. Computed tomography of the paranasal sinuses showed a 3.8 × 1.8 x 3.7- cm enhancing soft tissue density in the left nostril. The mass obliterated the left nasal cavity and caused deviation of the septum to the right. The patient underwent an endoscopic excision and histopathologic examination confirmed the diagnosis of Schwannoma. Postoperative recovery was uneventful and no recurrence was seen in the follow-up period.

Schwannoma in the nasal cavity: A benign nerve sheath tumor at an odd location

“…Schwannomas generally present as solitary lesions without any associated genetic syndrome but when there are multiple schwannomas in the same individual, neurofibromatosis Type 2 should be ruled out in these patients. Schwannomas are benign and slow-growing tumors that rarely undergo malignant transformation [1][2][3]8,9].…”
