Background. Metastatic bronchial tumors from colon cancer generally have a poor prognosis. Case. The patient was a 44-year-old woman who presented with hemoptysis, wheezing, and dyspnea and was admitted 6 years after resection of sigmoid colon cancer. Whole-body CT detected many tumors in the trachea and bronchi we diagnosed metastatic bronchial tumors from colon cancer. Laryngeal arterial embolization was performed on the day before surgical endoscopy to reduce the risk of bleeding and the tumor volume. An extracorporeal membrane oxygenation was used because of the high risk associated with tracheal stenosis. Airway management was carried out with a laryngeal mask, and multiple protruding lesions were excised by electrosurgical snaring. The symptoms of airway stenosis disappeared after extubation. Radiation and chemotherapy were administered and the tracheal tumors showed complete response. Conclusion. This report describes a rare case of airway stenosis due to multiple metastatic bronchial tumors that developed 6 years after resection of colon cancer. Surgical endoscopy sufficiently improved the airway stenosis and overall condition to allow the administration of additional treatment.
