Book excerpt: ​This book is derived from notes taken during a dermatology residency and it represents a comprehensive yet condensed approach to a dermatology curriculum, listing every entity with only the most important and testable facts and mnemonics. There is an intimidating large amount of material for young dermatologists and other doctors with an interest in dermatology to learn, and this guide puts it all into a concise and manageable context. Further, introductions to the dermatology physical exam and dermatopathology, as well short guides describing the basics of medications, basic science, cosmetics, and surgery are included. The goal of this guide is not primarily to help with visual identification of diagnoses, but rather to help young dermatologists learn to create differential diagnoses and learn all the important facts for myriad diseases. Given its unique approach, this guide will serve new residents well in quickly adapting to a new field, and also, it will serve senior residents as quick review of all topics in preparation for in service and board examinations. In general, there are very few dermatology board review books of any kind and therefore this book will immediately have a market among dermatology students, residents, rotators, and faculty.
