Fitzpatrick's Dermatology in General Medicine, fifth edition (DIGM) is still the mother of all dermatology textbooks. Its liberal use of tables, diagrams, and high-quality color photographs (within the chapters as opposed to in a separate reference section) makes the fifth edition even easier to read than previous editions. The book would be even more reader friendly if it had more chapters formatted like chapter 168, "Skin Changes and Diseases in Pregnancy," which provides disease-specific history, clinical features, histopathologic characteristics, course, differential diagnosis, and treatment options. It is a comprehensive reference book that adequately covers most cutting edge issues (although, like any textbook, by the time of publication, it was already out of date in the discussion of some basic science and new treatment advances).
