Placental examination can be frustrating because of a perceived lack of usefulness and other limitations. A systematic examination employing a topographic approach that will eliminate gross omissions is described. This approach is used at the time of gross and histological examination. Histologically, the umbilical cord is examined from the surface to the inside, while the amniochorial membranes and placental disc are examined from the foetal to maternal surfaces. It is possible to accrue useful information when the placenta is examined this way. This information then can be correlated with the clinical details and indications for the placental examination.
