It is our pleasure to bring you this atlas of skin disorders. We are hopeful that by seeing this wide array of images, you may more easily recognize and diagnose skin conditions in your own patients. If our efforts result in a better outcome for one patient, then they were worthwhile. Our atlas is an accompanying volume to Andrews' Diseases of the Skin. The chapters and entities follow the organization of Andrews', making explanatory text unnecessary and allowing you to enjoy the superior photographs in an uncluttered fashion.
Dermatologic diagnostic abilities are learned through repetitive exposures to patient presentations. The present volume of over 3000 pictures, combined with the main textbook, will be an outstanding resource to learn the depth and breadth of our specialty.
The four authors have benefitted by spending a combined 60 years in academic medicine, taking photographs along the journey. Additionally, the resources of our institutions and many friends have allowed a stunning array and variety of presentations to be represented. Bill James recognizes Richard Odom, MD, my teaching chief, who allowed myself and fellow resident Robert Horn to make copies of his best slides. Bill also thanks past residents and faculty of the Walter Reed Army Medical Center. Tim Berger has shared photographs from his experiences at the University of California at San Francisco. Bill and Rob both wish to thank the faculty and residents at the University of Pennsylvania, who generously shared their expertise. Dirk thanks the members of Brooke Army Medical Center who have contributed to the image collection in San Antonio. Pat wishes to recognize that the considerable resources of Paul Honig, MD's personal collection, as well as the combined image database of the current faculty at Children's Hospital of Philadelphia, were made fully available. These photos of pediatric patients enhance the atlas considerably. Finally, James Fitzpatrick, MD, also generously shared photographs taken by the faculty and staff of Fitzsimmons Army Medical Center. We call out all of these wonderful people, as they are not recognized individually in most of the photographs. In some cases when a photograph was obtained from a specific faculty member or resident, their names appear in a "Courtesy" line under the image.
You will find over 50 contributors individually recognized in the figure legends. These range from institutions in Taiwan, Brazil, and Japan, to individuals in Singapore, India, Thailand, Portugal, and the Philippines, to the National Institutes of Health and faculty from a variety of academic centers around the country. Several individuals deserve special mention: Steven Binnick, MD, is a superb dermatologist from Plymouth Meeting, Pennsylvania. When asked if he would make available some of his excellent photographs for this atlas, he simply donated his collection and was happy they would be used to educate others. Curt Samlaska, MD, trained at Walter Reed with Bill. He is an outstanding dermatologic photographer and contributed many photos of his patients from Hawaii and his practice in Henderson, Nevada. Doctors Shyam Verma and Archana Singal, close friends from India, shared many of their wonderful images. Dr. Leonard Swinyer took many outstanding photographs during his years in private practice. He gave his collection to the Dermatology Departments at the University of Utah and the Oregon Health Sciences Center. We thank all of them for their generosity.
This wide array of altruistic physicians and many others individually recognized in the atlas have allowed us to demonstrate entities rarely seen in the United States. More important, we had the full spectrum of patient ages, skin types, morphologies, classic examples, and disease subtypes available to us in choosing the best 3000+ images that make up this volume.
Charlotta Kryhl, Laura Schmidt, and Manchu Mohan from Elsevier assumed primary roles in the compilation of the book in a most expert and responsive manner.
No words of thanks could be complete without acknowledging the personal sacrifices of our families in allowing us the opportunity to pursue our professional dreams. Those include all of the individuals listed in the dedication.
Finally, to all of our past patients who generously allowed us to take their photographs, we hope this work helps fulfill your desire to aid future sufferers of skin disease recover more rapidly through earlier recognition and diagnosis of their conditions.
