Bruce R. Smoller, md, concisely reviews for practitioners and students alike the science of immunopathology, its many basic laboratory tools, and their multiple diagnostic uses in actual clinical case studies. The author presents in an easily digestible form a dictionary of antibody probes, summarizing for each antibody the targeted antigen and its cellular function, its diagnostic utility, and, when available, its sensitivities and specificities for identifying various neoplasms. Real clinical cases from the author's practice demonstrate the benefits of immunopathology.

It is a pleasure to introduce this new book, Clinical and Pathological Aspects of Skin Diseases in Endocrine, Metabolic, Nutritional, and Deposition Disease, edited by two of my friends and respected colleagues, Franco Rongioletti and Bruce R. Smoller. In fact, I was very ent- siastic when I learned that they were preparing this work. Although endocrine, metabolic, w, and deposition diseases are regularly included in general textbooks of dermatology and d- matopathology, one gains the general impression that these topics receive little emphasis and are mainly included for completeness. The prospect of having all of this information in one volume, lovingly described and detailed by experts in the feld, should be of great interest not only to dermatologists, pathologists, and dermatopathologists but also to internists and en- crinologists, who may well gain a different perspective on these disorders. As a derma- pathologist, I am also pleased that this project has been organized and undertaken by two distinguished authorities in cutaneous pathology. This assures a close integration of histo- thology and other laboratory techniques with the clinical aspects of these disorders, which will make it possible - perhaps for the frst time - to view these conditions in a truly comprehensive way. So I invite you, the reader, to open this volume and dig in; be prepared for an eye-catching, intellectually stimulating, and ultimately rewarding experience! Charlottesville, VA James W.
