The second edition comprehensively reviews the wide field of rare pulmonary diseases. Issues such as less common diseases affecting the airways, systematic disorders with lung involvement, interstitial lung diseases, and many other orphan conditions of the lungs are explored in this book. The progress and advances made in the field and the limited number of patients presenting each condition makes it very difficult for clinicians to be up-to-date in this field. Readers will discover how to diagnose and manage these rare orphan diseases.
