In this tenth edition the authors have attempted, very successfully, to correlate descriptions and concepts of disorders of the skin with general medicine and biology —to answer the question "What is going on?" rather than to content themselves with classification. This approach has necessitated radical rearrangement and the inclusion of much material not to be found in the ninth edition. Also added are ten color plates and a large number of new illustrations. The bibliography is extensive and includes many additional comments intended primarily for the special student. The book should serve as a valuable work of reference for the internist.
