There are many tomes available detailing the histopathological features of both general surgical pathology entities and organ specific pathologies. In addition, several texts present aspects of developmental, fetal and placental pathology. However, for the specialist paediatric pathologist with a significant paediatric surgical specimen workload, and for the practising general surgical pathologist faced with reporting paediatric surgical specimens, although information regarding many of the specific entities affecting childhood is available in the former texts, such information requires searching of many disjointed books. Therefore, the aim of this publication is to present a comprehensive and detailed account, which brings together and covers all, or at least most, paediatric surgical pathological entities in a single volume, to allow rapid access for day-to-day use by practising histopathologists. The focus is on practical diagnostic issues throughout. Concentrates on the diagnostic and management issues that are relevant to the surgical pathologist when signing out a report: ie variant histopathological appearances, what the surgeon needs to know about grading. Comprehensive coverage of all entities that occur in children and adolescents.Provides the general surgical pathologist more used to interpreting adult specimens with a complete guide to all of the histopathologic differences in appearance compared to similar diseases in adults. Superb, high quality full color illustrations of key aspects of various diseases (histopathologic, molecular and clinical features) throughout.Provides a complete visual guide to paediatric neoplastic and non-neoplastic lesions will allow rapid identification of tumor or tumor-like lesions. Includes the latest techniques in immunohistochemistry and molecular genetics in an integrated manner.Provides comprehensive information on all of the investigative contexts relevant to formulating an accurate. diagnosis. Information organized simply and consistently throughout in bullet point format.Helps the users find what they’re looking for quickly and easily. Extensive use of tables to list all of the possible differential diagnosis of each tumor and tumor-like entity. User-friendly summary of key points to be considered in problem areas presented in a way that makes it ideal for a busy surgical pathologist.

Provides in-depth clinical reviews on hematopathology, offering actionable insights for clinical practice. Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field. Authors synthesize and distill the latest research and practice guidelines to create clinically significant, topic-based reviews.
