“This updated edition serves as an in-depth reference for understanding immune-mediated skin diseases. … This rich resource not only contains information for immunologists and practicing dermatologists but also serves as a guide on a daily basis. For example, this book can be used by residents as a teaching tool and is a helpful source of review for the boards.” (Chrystal Paulos, Journal of the American Academy of Dermatology, Vol. 78 (5), May, 2018)
