Book excerpt: Addresses one of the most difficult areas in surgical pathology, non-neoplastic disorders of the lower respiratory tract. Recognising the need for a multidisciplinary approach to the successful diagnosis of many of these diseases, a pulmonologist and two radiologists have been included as authors to supplement the pathology contributions. With their clinical and radiological expertise, the authors have greatly enhanced the pathology descriptions resulting in a book of almost 1000 pages, with a total of 1,185 colour and 284 black and white images, including pathology as well as radiology illustrations. When appropriate, the importance of clinical, radiological, and pathologic correlation is emphasised. The radiology images include characteristic manifestations on chest radiography and high-resolution computed tomography. This reference will be helpful to clinicians, radiologists, and pathologists seeking a better understanding of this difficult subject.
