Paediatric pathology is unique as ssubspecialty of pathology in that it is defined by an age group rather than an organ system or process. As such, th esubspecialty encompasses the study of disease from embryonic life to young adulthood. The tumours that occur in infants and children are distinct from those that develop in adults, and they often exhibit unique clinical behaviour, so that specific therapuetic protocols are required. Prior to the publication of the first edition of this book in 1992, the only other US-based text that existed was a 1975 Mosby publication, Kissane, Pathology of Infancy and Childhood, 2,e. The author had elected not to undertake a 3,e thus creatin gan opportunity that Stocker and Dehner seized upon. As such, this book was designed to be a comprehensive volume on all major aspects of the pathologic anatomy of childhood disorders ranging from chromosomal syndromes and neoplasms to forensic pathology.
