Vashi Preface Vashi and Maibach’s Dermatoanthropology of Ethnic Skin and Hair is a com- prehensive text that extensively examines cutaneous disease in persons with skin of color. The breadth of knowledge in this book encompasses the wide scope of dermatologic disease with 26 distinct and unique chapters. It serves as a guide to the diagnosis and treatment of skin disorders for those populations with darker skin types. This book provides an overview of medical, surgical, and cosmetic dermatology in addition to providing an extensive anthropological and basic science background to fully understand skin disorders in persons of color. Topics of discussion include anthropology of skin and hair, biophysical properties of ethnic skin, structure and function of the skin, physiologic pigmentation, mucosal lesions, acne, rosacea, inflammatory disorders, infections, autoimmune disorders, connective tissue dis- ease, hyperpigmentation, hypopigmentation and depigmentation, keloids, scarring, pediatric disease, alopecias, adnexal disorders, common cosmetic concerns and treatments, and cultural considerations. As the domestic and worldwide populations evolve, dermatologists will increasingly have to recognize nuances in skin disorders that occur in darker skin. We hope that this book helps dermatologists with the challenges involved in treating those with darker skin tones in culturally appropriate ways. It has been a great honor to have leaders in the field of dermatology and ethnic skin contribute to this book. We are forever grateful for the hard work and insights that were shared for this important contribution to dermatologic literature. Boston, USA Neelam A. Vashi, MD San Francisco, USA Howard I.
