Book excerpt: This book is a richly illustrated account of the clinical features, microscopic anatomy, and management of acne, acne-like disorders, and rosacea. The coverage includes all aspects of these diseases, from physiology to pathology, bacteriology, and endocrinology; special emphasis is placed on histopathology. Moreover, the full spectrum of pharmacological and physical methods of controlling the disorders are critically examined and the widely experienced team of authors present in detail their personal strategies for successful treatment. Since it was first published, Acne and Rosacea has become a well-known classic. This fourth edition has been completely revised and updated, with entirely new chapters on topics such as etiopathogenesis, auto-inflammatory acne syndromes, the role of nutrition, and novel therapies. The text is supplemented by selected references and a wealth of clinical and histopathological pictures, including additional high-definition photographs. The book is designed for all those physicians – dermatologists, general practitioners, pediatricians, gynecologists, pharmacologists, and surgeons – who must identify and treat the many different forms of acne and rosacea.
