Perfect for medical students, dermatology first-year residents, dermatology nurses, physician assistants, nurse practitioners, and other primary care physicians, Lookingbill & Marks’ Principles of Dermatology is a concise, abundantly illustrated, everyday reference for dermatologic diagnosis and therapy. This text is a true primer: it assumes no prior knowledge and is intuitively organized by morphology (appearance) rather than etiology (cause). A reader favorite through six outstanding editions, this updated 7th Edition follows a consistent, templated approach with key points, clinical pearls, differential diagnosis, and tables of first- and second-line treatments-making it easy to read and understand. Superb clinical photographs, full-color histopathology images, and corresponding cross-sectional line diagrams provide an easy-to-understand framework for categorizing skin conditions.
