The surgical pathologist examines the placenta.

In this chapter, placental development, morphology, and indications for its examination have been reviewed. Techniques for placental examination with practical suggestions applicable to the surgical pathology laboratory have been pointed out. Several specific examples of clinical conditions in which morphologic alterations within the placenta assist with or establish a diagnosis have been presented. It is hoped that this information will encourage pathologists to use this important organ more fully as a resource in diagnoses and patient care.
