An Unusual Finding of a Neurogenic Tumor of the Trachea: A Tracheal Schwannoma

Abstract

We report a rare case of a 57-year-old female patient with intraluminal tracheal obstruction caused by a benign schwannoma. She underwent successful bronchoscopic resection under general anesthesia, with no complications observed during the post-procedure follow-up. Tracheal schwannomas are exceedingly uncommon, and while conventional treatment involves surgical resection, bronchoscopic techniques, such as laser ablation, can be a valuable alternative, particularly for high-risk patients. Further studies are needed to explore the full potential of bronchoscopic interventions in managing tracheal schwannomas.
