Because 10% of all physician visits are related to illnesses that involve skin symptoms, every health care professional must be able to recognize medical problems of the skin. This book has long been the most widely-used resource for that purpose. This best-selling book reflects the tried and true format of the Color Atlas and Synopsis series: for each condition, there are one to two color photographs coupled with salient points of epidemiology, history, physical exam, differential diagnosis, laboratory and special examinations, disease course and up-to-date treatments. Brief overviews of pathogenesis are given in special boxed elements that include icons that identify the illness as rare, not so common, or common and low morbidity, considerable morbidity, and serious. In contrast to the other dermatology references, this is a quick-reference clinical guide. It provides synoptic content in the need-to-know areas of information that physicians want to access during clinical care. Features
