In no field of medicine has greater progress been made in recent years than in that pertaining to the diagnosis of neoplasms involving the tracheobronchial tree. Bronchoscopy can lay claim to much of the credit. In the era prior to the use of the bronchoscope in the diagnosis of bronchopulmonary conditions knowledge of tumors of these structures was based largely on observations at autopsy.
NEOPLASMS OF THE TRACHEA AND BRONCHI
Tumors of the Trachea.—Primary tumors of the trachea are uncommon, particularly in children. Richards and Dietrich1 reported the occurrence of primary fibrosarcoma of the trachea in an 8 month old infant. The symptoms consisted of wheezing and dyspnea of one week's duration. Tracheotomy was performed, with considerable relief of the dyspnea. The first bronchoscopic examination showed no abnormality; however, at a subsequent examination narrowing of the left bronchus was found. Death occurred rather suddenly about six months
