The purpose is to present a concise account, which will serve as the basis for a useful teaching aid, of the clinical and pathological features of neoplastic disease and tumorlike condi- tions in the fetus and infant. Throughout I have used my own material as fully as possible and have introduced accounts of personally studied cases supplemented by ones from other colleagues illustrative of the subjects under discussion. For the same reason, I make frequent reference to my own published articles and to earlier publications, Tumors of the Fetus and Newborn, and the chapter entitled Tumors in Potter’s Pathology of the Fetus and Infant(Refs. 1 and 2 of Chapter 1), the contents of which in many ways supplement the present work. Most photographs and tables have been produced from personally studied material, while others were taken, by permission, from various articles appearing in the literature. The atlas is addressed primarily to pathologists, but I hope that clinicians, resi- dents, and medical students in pathology and other medical specialties may find it useful and beneficial as a concise, easy-to-use, quick ready reference source.
