Single Stage Nasal Reconstruction for Solitary Neurofibroma Isolated in the Columella.

Abstract

Neurofibromas are benign peripheral nerve sheath tumors that can originate from several elements of peripheral nerves, including axons, Schwann cells, endoneurial fibroblasts, and perineurial cells. The occurrence of a solitary neurofibroma in the external nose, especially that isolated in the nasal columella, is extremely rare. To the best of our knowledge, only 4 cases of solitary neurofibromas in the external nose have been reported in the English literature: on the nasal dorsum, tip, and pyriform aperture, all originating from the trigeminal nerve. We report the first case of a solitary neurofibroma isolated in the nasal columella, which we found in an otherwise healthy 42-year-old man. We completely resected this tumor with a negative resection margin and performed reconstruction with a bilateral spreader graft and caudal septal extension graft using autologous septal cartilage. The postoperative course was successful in both cosmetic and functional results, with no sensory changes at the 1-year follow-up. Surgical treatment for this lesion was challenging due to the cosmetically obvious location and high rate of recurrence. A review of the literature highlights the clinical and histological characteristics, differential diagnosis, and management of solitary neurofibroma of the external nose.
