Placental Mesenchymal Dysplasia with Unique Chromosomal Abnormality and Unusual Histopathology: A Case Report and Literature Review.

Placental mesenchymal dysplasia (PMD), rare vascular and connective tissue placental anomaly can be associated with fetal intrauterine growth restriction (IUGR), stillbirth, Beckwith-Wiedemann syndrome (BWS), some chromosomal abnormalities, or phenotypically and genetically normal fetuses [1]. We reviewed a PMD case from our institution characterized by a previously undescribed chromosomal abnormality along with an unreported histopathologic finding.
