          Abstract

          Bronchial schwannomas are rare tumors that arise from Schwann cells and account for a very small percentage of primary lung tumors. This case report describes a rare incidental finding of a bronchial schwannoma discovered in the left lower lobe secondary carina via bronchoscopy in a 71-year-old female who presented with minimal symptoms.

            Optimal treatment for primary benign intratracheal schwannoma: A case report and review of the literature.

            Xiahui Ge, Fengfeng Han, Wenbin Guan … (2015)
            A 53-year-old male was admitted to Xinhua Hospital (Shanghai, China) due to coughing and dyspnea that had persisted for half a year, with aggravation of chest tightness and dyspnea for 1 week. Chest computed tomography (CT) revealed a mass within the distal third of the trachea. Flexible bronchoscopy confirmed an ~2.0 cm, smooth, tan-colored mass in the trachea, 2 cm above the carina. Endoscopic resection by argon plasma coagulation combined with electronic snaring was applied, however, recurrence was found 2 weeks later. Finally, the tumor was completely removed by surgery and the post-operative course was uneventful. Since schwannoma is rare in the intrapulmonary region and extremely rare in the trachea, a review of 51 cases of primary tracheal schwannoma previously reported in the English literature was performed. The majority of cases occurred in adults and were usually located in the distal third of the trachea. The predominant tumor size was 1-3 cm and airway obstruction symptoms were common. Half of the patients were misdiagnosed with asthma, and CT scan and bronchoscopy were contributory to the correct diagnosis. The treatment of choice depended on the patient's condition, however, surgery should be chosen in the event of local recurrence following endoscopic treatment.

              Primary tracheal schwannoma: one case report and a literature review.

              Thomas Lequeux, E Reyt, Marie-Hélène Laverierre … (2005)
              We report a case of primary tracheal schwannoma causing symptoms of airway obstruction in a 51-year-old woman. There was no history of pulmonary disease. The patient had been coughing and suffering from progressive dyspnea for over 1 year. Medical treatment with bronchodilatators had no effect. Computerized tomography and bronchoscopy demonstrated a polypoid mass located inside the trachea's cervical segment, obstructing 50% of the lumen. A biopsy was not attempted because of the tumor's vascularity to avoid bleeding. Tracheal resection with primary anastomosis was performed. The diagnosis was confirmed with histological analysis. It revealed a benign neurogenic tumor of Schwann's cell origin. Schwannoma of the trachea is extremely rare. Only 23 cases have been reported previously. Most of them occur in adults (19/23, 82.6%) and are located in the lower trachea. They usually have a long natural history, causing symptoms only after they have attained a large size. The treatment of choice is surgical removal.
