Abstract
Tracheal neoplasms are rare, accounting for 0.10.2% of all malignant neoplasms [I.I. Davydovskyi, 1940]. Data from the database of the National Cancer Institute for Surveillance, Epidemiology and End Results indicate that primary tracheal carcinomas occur with an incidence of 0.7% of new cases per million people [Houston, 1963]. Patients with tracheal tumors can have severe airway obstruction. In addition to primary tracheal neoplasms, secondary tracheal affection may occur due to lesion of surrounding tissues such as thyroid, larynx, and lungs - 15.3%.
