A 29-year-old non-smoking female with a history of recurrent AML presented with worsening dyspnea. A CT scan revealed an 8 X 7 mm polypoid soft tissue nodule 8 mm distal to the carina in the left mainstem bronchus. She was brought to the operating room and a nearly obstructing soft fleshy tumor in the left mainstem bronchus just distal to the carina was removed with bronchoscopy. Pathology revealed a low grade mucoepidermoid carcinoma 0.8 cm in largest dimension with negative margins. The patient returned for a resection and was intubated with a right mainstem double lumen tube and placed in left lateral decubitus. After posterolateral thoracotomy, the azygos vein was divided to mobilize the esophagus and retract it laterally. Level 4 and 7 lymph node dissection were performed to obtain access to the anterior tracheal and subcarinal spaces. There was minimal dissection lateral to the trachea to minimize risk of ischemia. One centimeter of trachea just proximal to the carina was circumferentially isolated with umbilical tape for retraction. We bronchoscopically confirmed the location for transection and advanced a jet ventilator catheter distally. We resected one centimeter of left mainstem bronchus. We inspected the lumen of the airway to confirm no gross residual disease and confirmed negative pathologic margin before performing an end-to-end anastomosis with interrupted absorbable sutures under both jet and cross-table ventilation. Postoperatively, the patient had an uncomplicated course and was discharged without any supplemental oxygen on postoperative day 6. Final pathology was low grade mucoepidermoid carcinoma, T1aN0
