[Surgery of primary tracheal tumours of the salivary gland type].

INTRODUCTION: Primary tumours of the trachea are very rare and may develop from the tracheal salivary glands.

CASE REPORTS: We describe four patients operated on in our service between 2010 and 2017 of whom two had an adenocystic carcinoma, one a mucoepidermoid carcinoma and one a pleomorphic adenoma of the trachea. All were treated by resection and tracheal anastomosis with clear margins in three cases. The malignant cases received adjuvant treatment consisting of radiotherapy in one case and radiochemotherapy in the second. Immediate postoperative recovery was uncomplicated in all patients. One death followed the developement of post irradiation tracheal stenosis two years after surgery in a patient with an adenocystic carcinoma where the resection margins were invaded by tumour.

CONCLUSIONS: Resection and anastomosis of the trachea remains the best therapeutic option with a better prognosis when the resection is complete.
