Placental mesenchymal dysplasia: A case report

Abstract

The placental mesenchymal dysplasia is a not well known entity, with an uncertain etiology and under diagnosed. It is frequently confused with gestational trophoblastic disease because of its ultrasonographic features of a thick placenta, cysts and hypoechogenic images, with normal or slightly increased levels of human chorionic gonadotrophic hormone. The fetus is often viable and can manifest intrauterine growth restriction, prematurity or be associated with Beckwith-Wiedemann syndrome. We present a case report of a young woman with a preterm delivery, placentomegaly, suspicious of a partial hydatidiform mole and a low growth newborn.
