This third edition contains 56 contributions (most from American pathologists) that are arranged by body region or system. While continuing to stress the importance of routine light microscopy in daily practice, the revised edition reflects advances such as new stains, new classification systems, and recent research in immunohistochemistry and molecular biology. Among the new additions is the REAL classification of lymphomas (with a review of equivalents according to earlier classifications); an introduction to the proposed WHO classification of lymphoma; expanded discussion of cutaneous lymphomas; new classification of papillary urothelial neoplasms based on a meeting of the International Society of Urological Pathology; details of gastric and other intestinal tract stromal tumors; and a discussion of inflammatory lesions of the mesentery and retroperitoneum.
