Fisher's Contact Dermatitis is the classic reference text on contact dermatitis and patch testing. It is the principal text used in North America and to a great degree around the world. Since the first edition was published in 1967, it has been the essential text for dermatologists who see patients with contact dermatitis. Academic dermatologists, experts, and practitioners in this subfield use it as a reference for both teaching and writing. The seventh edition has been fully updated, including the mini-atlas and executive summaries of the chapters.
