Placental mesenchymal dysplasia in a normal female infant: a rare case report with follow-up.

ABSTRACT

Placental mesenchymal dysplasia (PMD) is a rare disorder of unknown etiology, which is often misdiagnosed as partial hydatidiform mole because of their similarity in ultrasonographic, gross, and histologic presentations. However, the treatment and prognosis of these two conditions are different. Patients with PMD often have intrauterine growth restriction, intrauterine fetal death, and Beckwith-Wiedemann syndrome, but there may also be a normal fetus. PMD with a normal female infant is extremely rare, and only a few cases have been reported. We report a case of PMD in a normal female infant and its follow-up results.
