Challenging Cases in Dermatology provides a strategic and analytic way of thinking about unusual dermatologic presentations. Every case presented within this book is a unique story, but the clinical decision pathways used to reach an appropriate solution are similar. A wide range of cases are covered including many extremely rare diseases and rare presentations of diseases that are not, themselves, uncommon. A familiarity with such unusual cases will provide the dermatologist with increased knowledge, a wider perspective, and innovative techniques that can be used to solve diagnostic dilemmas. The author has used his vast experience in practicing dermatology to create a visual reference for skin disease, with the emphasis on working through each case as presented, starting with the clinical data, histological slides, and other available investigations. Each chapter includes a brief discussion of each extraordinary case and includes epidemiology, pathogenesis, clinical and histological features, differential diagnosis, definite diagnosis, prognosis, and management.
