Color Atlas of Pediatric Pathology Aliya N. Husain J. Thomas Stocker Color Atlas of Pediatric Pathology Aliya N. Husain, MD • J. Thomas Stocker, MD The Color Atlas of Pediatric Pathology covers the broad range of pediatric diseases that a pathologist will likely encounter and is written by well-known leaders in this field. Coverage includes both frequent and less commonly seen cases, and each discussion presents a concise summary of the salient features of the disease along with expertly selected, high-quality color images. The Color Atlas of Pediatric Pathology is a practical working resource for every pathologist who sees pediatric cases as well as the pathology trainee. The atlas features approximately 1,100 high-quality images as well as important staging and prognostic (including molecular) parameters. Features of the Color Atlas of Pediatric Pathology include: n Comprehensive coverage of both common and uncommon diseases in pediatric surgical pathology n Chapters presented by a recognized expert n Practical presentations: concise text highlights diagnostic features making the atlas an outstanding resource for the practitioner n 1,100 full-color images 1.

CENTRAL NERVOUS SYSTEM AND NEUROMUSCULAR DISEASE 401 Peter Pytel Index 419 ix Pediatric pathology is distinct from adult pathology in many ways: types of diseases, genetic and molecular defects, therapies (including side effects and long-term complications), and outcomes. This is not only because of congenital malformations but also because infections and tumors that affect children are not the same as those seen in adults. One example is Wilms tumor, which is relatively com- mon in children but exceedingly rare in adults, with diagnostic and staging parameters distinct from adult renal tumors, and a cure rate of over 95%. Thus, pediatric pathology has been a boarded subspe- cialty in the United States and Canada since 1991. The majority of pediatric pathologists work in chil- dren’s hospitals; however, more than half of the pediatric cases are being seen by “general pathologists” in various practice settings. Thus, there continues to be a need for all pathologists to keep current in their diagnostic skills and knowledge of pediatric pathology and this atlas has been written with those residents, fellows, and general pathologists in mind. It is meant to serve as a handy reference for people who see pediatric cases infrequently and may have no special expertise in the subject. It cannot replace a comprehensive textbook; rather it should be used in addition to one. For years, one of us (JTS) had wanted to use his extensive collection of photographs to illustrate an atlas of pediatric pathology. You may wonder why such a book is needed in this age of “Google pic- tures.” We think there is considerable value to the student as well as the practicing pathologist to see illustrations selected by “experts,” such as the chapter authors in this book. In addition, the accompa- nying text concisely summarizes the pertinent features of each disease. Thus, rather than sifting through the thousands of items brought up in nanoseconds by any of the search engines, one can turn to an atlas such as this when faced with an uncommon or rare diagnostic specimen. The Color Atlas of Pediatric Pathology is organized in a traditional manner with each chapter devoted to a specifi c organ system. The authors for each chapter were chosen for their knowledge, and were asked to cover common as well as selected uncommon diseases that every pathologist would need to know about. Because this is an atlas, the focus is on illustrations with supporting text; only selected references are given. This book brings together the experience and expertise from many institutions, which add to its value. As with any multi-author book, there is some variation in how each chapter is written and illustrated. We hope our readers will fi nd the Color Atlas of Pediatric Pathology to be a valuable resource in their diagnoses of pediatric cases.
