A comprehensive – yet compact – reference guide for dermatologists in training or in practice The Handbook of Dermatology consolidates the essential information required for best-practice patient care into one pocket-sized volume. This indispensable reference guide enables practicing and prospective dermatologists to easily look up information on a wide range of dermatological diseases and quickly access the algorithms, protocols, guidelines, and staging and scoring systems that are vital to both clinical practice and exam success. Written and edited by former residents and attending physicians, the handbook contains up-to-date information on general dermatology, surgery, and therapeutics. Now in its second edition, this useful guide presents data in outline, bullet-point, and table formats to ensure easy and efficient retrieval. The table of contents and index have been revised and reorganized to allow for faster and more intuitive searches. New material includes a work-up quick reference table, a melasma work-up and management algorithm, information on dermatologic signs and dermoscopy, and more. Updated subject areas include drugs and therapies, fillers and toxins, UV and sunscreen, peeling agents, venous disease, propranolol, and contact dermatitis. Offers up-to-date information reflecting new gene discoveries and other advancementsUpdated to cover a range of new medications and treatments, including laser surgeryCompact and accessible design for everyday clinical useFeatures new clinical practice guidelines and algorithms, as well as helpful illustrations and data tables The Handbook of Dermatology is a valuable resource for trainee and practicing dermatologists, general practitioners, and medical students.
