The Pathology of the Human Placenta

Part of the Handbuch der Speziellen Pathologischen Anatomie und Histologie book series (SPEZIELLEN, volume Teil 5)

Abstract

This presentation of the diseases of the placenta differs in many ways from the first such treatment in these volumes by the eminent Robert Meyer. It is a deliberate attempt to bring together the practical information which has been gathered about the pathology of this complex organ and to make it available to the practicing pathologist as well as clinician. Despite the ready availability of the placenta for study, the pathologist is often ill-prepared to interpret lesions which he may find. Moreover, it has been difficult for him to find reference material, published commonly in journals and books with which he is not familiar. Furthermore, the interpretation of lesions affecting the placenta seemed less challenging since the organ had served its function, was to be discarded and presumably little of significance could be expected from such a retrospective study.

Possible relation to intrauterine malnutrition. In reply Falkner (ibid. i, 869, 1965) finds the conclusion unwarranted that hypoglycemia of the smaller twin may be the cause of mental retardation. This author also points to the importance of determination of glucose levels in the larger “controls” and zygosity studies.Google Scholar
