This excellent monograph should be in the library of everyone who treats respiratory diseases. The first chapter, dealing with anatomic aspects, is followed by one on anomalies of the tracheobronchial tree. Various conditions affecting the bronchi, such as acute laryngotracheobronchitis, vascular defects affecting the tracheobronchial tree, and their complications are then examined. Tumors of the trachea, although rare, are also considered. There are chapters on chronic bronchitis, bronchiectasis (which is considered more completely than most of the other subjects), foreign bodies in the tracheobronchial tree, tuberculosis of the tracheobronchial tree, and bronchogenic carcinoma. There are also shorter chapters on alveolar cell tumor of the lung, bronchial adenoma, benign bronchial tumors, broncholithiasis, bronchostenosis, atelectasis, bronchial obstruction by compression, bronchoesophageal and tracheoesophageal fistulas, asthma, syphilis of the tracheobronchial tree, hemoptysis, and trauma. The monograph is written in an easily readable style and can be digested in a short time.
