Written as a response to the increasing utilization of minimally invasive procedures in children, this state-of-the-art book provides a comprehensive review of pediatric cytopathology with histopathologic correlation, focusing particularly on those entities unique to the pediatric population and highlighting differences between children and adult patients. As most pathologic diagnoses require knowledge of clinical presentation and/or imaging features, these are integral parts of the work-up in each chapter. This comprehensive guide provides optimal use of the newest diagnostic techniques (including molecular, genetic and immunohistochemical studies) to help overcome diagnostic challenges. The book is illustrated with more than 1000 high-quality color images and a password in each copy of the book provides the reader with full electronic access to all text and images. This book will provide a practical resource for practicing pediatric pathologists and cytopathologists, and a valuable educational tool for the residents and fellows in training.
