Partial molar pregnancy with fetal survival: An unusual example of confined placental mosaicism: PDF Only

Background: A pregnancy with a partial molar placenta and a normal fetus is a rare condition. Few guidelines exist for antenatal evaluation and management, particularly with respect to selecting cases for conservative management.

Case: Cytogenetic analysis of chorionic villi showed a triploid placenta, and both amniotic fluid and blood indicated a diploid fetus. The pregnancy resulted in a normal newborn.

Conclusion: This disorder appears to be due to confined placental mosaicism.(Obstet Gynecol 1993;82:716-9)
