This is the second edition of a landmark dermatopathololgy text and atlas describing inflammatory skin diseases. It is unique in providing an algorithm in differentiating one disorder from another. The book intends to provide the reader with a novel approach to use patterns consistently seen in inflammatory skin diseases to logically and systematically differentiate a diagnoses. Given the complexity in interpreting inflammatory skin biopsies as opposed to neoplastic lesions, these are worthy objectives. The authors meet these objectives, and more. The intended audience includes pathologists, dermatopathologists, dermatologists, and residents. The lead author is considered the world's expert in interpreting inflammatory skin diseases. Many of the authors, such as Dr. Bennin, are active in teaching dermatologists the algorithmic method. This impressively featured text and atlas includes some of the finest color photomicrographs currently published. Most micrographs are taken at different levels of magnification. References are extensive, and a bibliography even provides a little history on the skin diseases. Diseases are extensively detailed in the section on pattern analysis as well as chapters specifically discussing the disease entities. This book should be considered one of the most important dermatopathology textbooks ever written. It gives the reader a method of interpreting biopsy slides which is most logical and consistent. This new expanded and updated edition is a must have for every dermatologist or pathologist who interprets skin biopsy slides.
