This book acknowledges that clinical dermatology is a visual specialty. The route to diagnostic understanding is a combination of access to photographic material combined with a simple scheme for recognising primary skin lesions. Clinical dermatology is designed to help undergraduate medical students, general practitioners, general physicians (the secondary market) requiring a fundamental knowledge of dermatology, and trainee dermatologists. The book contains chapters which cover all the common skin diseases in the context of their underlying pathological processes and the way in which disturbances of the function of the skin produce recognisable physical signs. These are punctuated by short, sometimes witty learning points.
