Schwannoma of the nasal septum

Abstract Schwannomas are benign and slow growing tumors originating from the Schwann cells of peripheral nerve sheath. Schwannomas of sinonasal origin are rare (4%) however septal schwannomas are much more rarer. We presented a 31 year old female patient. At physical examination a pale gray, smooth polypoid lesion obstructing the right nasal cavity was detected. Midfacial degloving and endoscopic approach were combined for surgical treatment. The tumor was originating from posteromedial area of the septal nasal cartilage, close to the bony cartilaginous junction. Postoperative histological examination of the specimen showed a benign tumoral growth consisting of spindle shaped cells and immunohistochemical staining of the tumor proved septal schwannoma.
