This is the second edition of a book first published 15 years ago as "Dermatologic Drug Directory". The book was originally intended as a guide to the drugs required to treat skin diseases. However this new edition is far more of a pictorial aid to the diagnosis of common skin diseases. The first section of the book does still discuss Systemic Drugs, Topical Therapy, and the Side Effects of Drugs, but it then provides a large lavishly illustrated section on the Instant Diagnostic Criteria and Treatment of Common Skin Disorders. This book will be useful to students being introduced to dermatology for the first time, and also to practitioners who can refer to it in their day to day consultations.
