Abstract
Tracheal neoplasms occur infrequently, the majority of primary tracheal tumours in adults are malignant, and in 40% of cases it is adenoid cystic carcinoma, which can be asymptomatic for a long period of time. Surgical treatment can be justified even in advanced disease, because progression of tracheal tumour usually causes obstruction of airways. Improved long-term outcome seems to follow combined surgical resection and full-dose radiotherapy. Patients after resection of adenoid cystic carcinoma need careful and long-term observations to detect a relapse
