This is the eighth volume in the New Clinical Applications Dermatology Series. Awareness of relationships is of prime importance in der matology. Professor Scully and Dr Porter cover the skin and mouth in a comprehensive and informative manner. Mr Peter Wright effortlessly and concisely brings the eye and the skin together. Dr C. Rowland Payne both relates and speculates on the enigma of sarcoidosis. Pro fessor Elder concludes the book with a scholarly update on porphyria and the skin. I thank all the above for their fine contributions. This volume should have widespread appeal.
