TRACHEAL obstruction by a primary tumor is customarily treated by endoscopic methods, namely, piecemeal removal of tissue projecting from the wall of the trachea, diathermic cautery of the base of the tumor and dilation. Such procedures have sufficed to relieve many patients of their symptoms for months. Because a fairly large proportion of primary tumors in the trachea are cylindromas, which invade little beyond the trachea and grow slowly, control of the tumor may be possible for several years.
