Nasal Alar Schwannoma: An Unusual Case Report.
Abstract
[PURPOSE] To present the second known case of nasal alar schwannoma, first since 1973, with important considerations for surgical management.
[CASE REPORT] We present the case of a 25-year-old male with a 5-year history of progressively enlarging, non-tender, right alar mass with resultant ipsilateral nasal congestion and dyspnea secondary to nasal valve collapse. The mass was located cephalic to the mid-lateral aspect of the lower lateral crural cartilage, which extended to the pyriform aperture. The mass was removed in an en bloc fashion using an endonasal rhinoplasty approach with placement of an alar batten graft for valve stabilization. The surgical pathology of the mass was consistent with schwannoma.
[CONCLUSION] Regardless of the rarity, schwannoma should remain on the list of possible etiologies for a nasal alar mass. Depending on the size and concurrent mass effect, the external nasal valve may be compromised requiring careful evaluation and operative stabilization for optimal postsurgical outcome.
