A non-smoker 31-year-old female with a history of Turner syndrome and Follicular thyroid carcinoma treated by total thyroidectomy and radical neck dissection presented to her follow-up visit at the oncology department. The patient did not report symptoms such as dyspnea, cough, wheezing, or neck masses. No tumors or abnormal breath sounds were present during the physical examination. The follow-up computed tomography (CT) scan incidentally showed a partial airway obstruction secondary to a 14 mm endotracheal tumor. There were no lymphadenopathy or mediastinal masses. Flexible bronchoscopy confirmed a 14 × 8 × 5 mm, smooth and oval-shaped tumor at the left posterior tracheal wall.

The patient was submitted for surgical resection by an anterior cervical approach. During surgery, the identification of the tumor was made by bronchoscopy. The anterior tracheal wall was incised distally to the tumor at the level of the fourth tracheal ring and the tumor was resected at its pedicle. The tracheal wall was closed with interrupted 3–0 polydioxanone stitches. A closed, active Blake drain was left in the paratracheal space to avoid subcutaneous emphysema. It was removed on the seventh postoperative day.

The histologic examination showed an Antoni A cellular pattern, composed of spindle cells with palisading nuclei areas, without mitotic activity or necrosis areas, being compatible with schwannoma. Four weeks later, a control bronchoscopy showed a normal healing process, without stenosis or tumor persistence at the surgical site. Two months after surgery, the patient resumed her daily life activities. At present, 14 months since the procedure, the patient continues asymptomatic, with a normal functional status, and still under clinical surveillance without local recurrence.
