The placenta is a fetal organ, composed of fetal DNA and as such reflects the fetal phenotype. The placenta consists of an umbilical cord, fetal membranes (amnion and chorion), and the placental disc which in turn is comprised of villous tissue. Both maternal and fetal disorders have placental sequelae and placental abnormalities can affect both maternal and fetal well‐being. As such, placentas are often helpful in future maternal and neonatal healthcare. Thus, examination of the placenta is important for both mother and infant. On this basis, a list of indications for placental examinations has been created by a multidisciplinary group of pathologists, maternal‐fetal‐medicine specialists, and neonatologists that, if followed, will ensure that the vast majority of placentas that ultimately show any significant pathology will be examined (Arch Pathol Lab Med, 121, 1997, 449–76). This list include fetal, maternal, and placental indications. This chapter will discuss those indications as well as give a brief overview of macroscopic placental examination and procedure.
