Placental mesenchymal dysplasia: a diagnostic dilemma

Placental mesenchymal dysplasia is a rare placental anomaly characterized by placental enlargement, dilatation and congestion of chorionic plate vessels, and villous edema without signs of trophoblastic proliferation. It is often confused with partial hydatidiform mole. It was first diagnosed in 1991 and the reported incidence is 0.02%. We hereby report a case of a 20 years PGR at a period of gestation 26 weeks 5 days with placental mesenchymal dysplasia. PMD is a rare entity that needs to be distinguished from molar pregnancy to prevent unnecessary termination of pregnancy. Once suspected, these patients should be treated as high-risk pregnancies as they are associated with intrauterine growth restriction (IUGR), intrauterine devices (IUD) and congenital anomalies.
