Schwannoma of the nasal columella: a rare presentation and surgical management through open rhinoplasty

Schwannomas are rare benign tumors arising from Schwann cells, with infrequent occurrence in the nasal cavity and paranasal sinuses. Even more uncommon is their presence in the nasal columella, where only a few cases have been reported. We report the case of a 64-year-old female presenting with a slow- growing, firm, non-tender mass in the left nasal vestibule, arising from the membranous septum. The lesion measured 1.5×1.2 cm, causing partial nasal obstruction. The patient had a complex oncological history, including treated breast cancer and suspected CNS metastases. Computed tomography (CT) imaging revealed a well-defined hypodense mass at area I of Cottle. Complete surgical excision was performed via open rhinoplasty, allowing optimal access and aesthetic preservation. Histopathology revealed Verocay bodies in Antoni A pattern. Immunohistochemical staining was positive for S-100 and vimentin, confirming the diagnosis of schwannoma. Postoperative recovery was uneventful. This case highlights a rare location of sinonasal schwannoma and supports open rhinoplasty as an effective approach for diagnosis and treatment, providing both functional and cosmetic benefits.
