After collecting the pictures of difficult, complicated, and unusual cases published in the journal and from his clinical prac- tice, he compiled and edited the atlas. The atlas consists of 387 cases and 1215 pictures including clinical, histopathological, and other laboratory findings. The pictures are clear, true to life, and sufficiently big. It is really a color atlas of high quality and provides a valuable reference and textbook for dermatologists. This atlas is illustrated and explained in English, and undoubtedly, this makes it much easier for dermatologists outside China to read and understand the dermatology in China, such as what are the difficult and complicated skin diseases and how do they manifest. I believe this publication will broaden the international academic exchanges, enhance mutual understanding between Chinese dermatologists and their foreign counterparts, and promote the development of dermatology of China. I warmly congratulate the publication of this atlas edited by Professor Zhu Wen-yuan and other contributors. Nanjing, China Wen-Yan Xu v Foreword I am eagerly awaiting and anticipating the publication of this most important volume on skin diseases in the Chinese population. For Western dermatologists, the world of Chinese skin and skin diseases is still largely a mystery. We know that all of the common diseases must occur in this huge and diverse population, but there must be many unusual variations on the common as well as many unusual and rare disease entities that are still uncommon or unknown outside of China. Therefore, the images in the atlas will tell the long-awaited story of Chinese skin and skin disease to the outside world. The importance of this work is further underscored by the considerable intermingling of our populations that has occurred in recent years due to intense commercial interactions, ever-more common tourism, and visitations among relatives of Chinese in all parts of the world. It will be important for the Western dermatologist, therefore, to have this volume close at hand as a reference work during his/her increasingly frequent interactions with these groups of patients. Finally, increased awareness will not only improve diagnostic capabilities but also open up new treatment options for formerly isolated patients with both common and rare skin diseases. Therefore, I must once again congratulate you on this important effort. University of California San Francisco Peter M. Elias San Francisco, CA, USA Dermatology Service and Research Unit (190) Department of Veterans’ Affairs Medical Center San Francisco, CA, USA vii Preface China is the third largest country and comprises 9.6 million square kilometers. It has the world’s largest population, including 56 nationalities and 1.3 billion individuals, and it is noted for its 5000-year history of ancient civilization. Increasing evidence suggests that there is no ethnic preponderance for skin diseases between the Chinese population and foreigners. Based on these considerations, China undoubtedly comprises the largest patient population of rare to challenging skin disorders. China has a unique geographical environment and diverse climate. Thus, it is likely that the same disease may develop various clinical manifestations and out- comes. We propose that the overwhelming majority of skin diseases recently discovered over- seas will soon be identified in China. Moreover, I would like to confidently predict that in the imminent future, an increasingly greater number of novel skin entities will be identified and investigated by Chinese dermatologists if they take advantage of these conditions. Furthermore, the process of new disease discrimination will be accelerated in terms of the large number of registered dermatologists. According to statistical data in 1995, China had 11,144 registered dermatologists. These individuals serve different hospitals at unequal levels throughout the country. As living standards increase, it becomes increasingly affordable to obtain better medical care in advanced hospitals. Diseases that were once misdiagnosed may now be recognized with the availability of more advanced medications. Therefore, many rare and challenging skin diseases will be consistently identified and will accordingly require pub- lication in journals or books. The practice of dermatology is based on a visual approach to clinical disease. Visualization also plays a critical role in how new information is integrated into pre-existing frameworks, which serve as the hard drives for the development of modern dermatology. Thus, I have encouraged myself to implement a meaningful publication project that comprises an atlas for rare skin disorders in China. I am an emeritus editor-in-chief for a well-known journal, the Clinical Journal of Dermatology, in China. This journal has been clinically oriented since its debut in 1980. Articles that describe case reports, clinical research, and treatment investiga- tions are preferentially published. Although this journal was initially a quarterly journal, it soon changed to a bimonthly publication. In 2002, as the journal received more valuable sub- missions that were waiting to be published, it transitioned to a monthly publication with all illustrated pictures printed on coated paper in color. The journal has published many valuable articles regarding rare and challenging skin diseases in Chinese. In my opinion, the articles published in this Chinese journal should not be considered incompetent by peers outside China. I believe that language barriers predominately limit the distribution of these papers outside China. I realized, one day, that I had a dream to compile a splendid atlas for the wonderful cases described by outstanding Chinese dermatologists for more than four decades. This thought was cultivated with our assiduous perseverance and continued to develop until 2008, when the book Atlas of Difficult Skin Disorders was published ahead of time at the second requests of domestic readers and peers. In this book, the commitment of visual learning is reflected in the use of 1215 pictures related to 387 rare skin diseases. The majority of the clinical pictures are integrated with pathological images and English legends, which attempt to provide weighted clinical information. This atlas has 274 outstanding authors in China ix x Preface who contributed at least one case illustration that is of high didactic value to dermatologists. This book has received a steady increase in its popularity and was honorably awarded the Three Specialties and One Hundred Each Program for Original Publications in 2008, which was issued by the China General Administration of Press and Publication. However, my progress has never slowed down. The world is currently in an era of globalization, which is characterized by mass migration. For western dermatologists, the world of Chinese skin diseases remains largely a mystery. As stated by Professor Peter M. Elias: “We know that all of the common diseases must occur in this huge and diverse population, but there must be many unusual variations on the common as well as many unusual and rare disease entities that are still uncommon or unknown outside
