Difficult to Diagnose Rare Diffuse Lung Disease presents the theoretical basis and practical aspects of differential diagnoses of rare lung diseases with the use of new method of probe-based confocal laser endomicroscopy (alveoscopy) of the distal respiratory region. Each chapter describes signs and symptoms of the disease and its typical and atypical manifestations. The book contains full color illustrations, including high-resolution histological microphotographs, CT-scans and confocal laser endomicroscopy images. In combination, these elements make this book an invaluable reference and guide for pulmonary researchers, pulmonologists, radiologists, and pathologists who wish to broaden their spectrum of knowledge in rare lung diseases.
