Products of Conception and Placentas
Products of conception is the term used for intrauterine tissue that is either passed spontaneously or removed surgically in early gestation. These specimens are usually sent for diagnostic or therapeutic purposes. The major goal is to verify that a gestation was present. This requires the identification of either fetal parts, chorionic villi, or trophoblastic cells. The presence of decidua alone is not sufficent for diagnosis. Molar pregnancies and placental neoplasia may also be identified, although these are much less common. Always be familiar with the patient’s clinical history, as this will help guide your examination.
