Diagnosing a genetic skin disease can sometimes be a difficult task for a dermatologist. This is especially true for genodermatoses-generally considered rare diseases seldom seen by practicing clinicians. As a result, professionals often have little experience with their diagnosis. The Atlas of Genodermatoses presents a unique collection of such cases gathered patiently over the course of the years by the authors. It provides an unsurpassed overview of the major genodermatoses encountered in practice, even if only on rare occasions. This book discusses almost 200 inherited diseases of the skin, hair, and nails. The entry for each disease includes its epidemiology, laboratory findings, genetics, pathogenesis, cutaneous and extracutaneous findings, differential diagnosis, disease course, complications, and follow-up and therapy, where appropriate. In addition to being a clinical primer, this atlas is also a work of scientific research. The new edition rewrites the classification of some diseases, adds some newly described conditions, and updates established information with the latest molecular genetic studies and references. Specialists in both dermatology and pediatrics should find the atlas an invaluable frontline resource in the clinic.
