Abstract：
Described as a rare anomaly of the placenta, with a reported incidence of 0.02%, mesenchymal dysplasia is a benign condition characterized by placentomegaly, grape-like vesicles and by microscopic features resembling those of a molar pregnancy, such as hydropic villi, cistern formation and dysplastic blood vessels. We report a rare case of placental mesenchymal dysplasia diagnosed in a pregnancy with early symmetric fetal intrauterine growth restriction and a normal karyotype. Based on this case report, we discuss the particularities of this condition, emphasizing the ultrasonography and histopathological findings.

被描述为胎盘的罕见异常，报告的发病率为0.02%，间充质发育不良是一种以胎盘肿大为特征的良性疾病，葡萄状囊泡和类似于磨牙妊娠的微观特征，如绒毛积水,水箱形成和血管发育不良。我们报告了一例罕见的胎盘间充质发育不良病例，在妊娠早期诊断为胎儿宫内生长受限且核型正常。根据这个病例报告,我们讨论这种情况的特殊性，强调超声检查和组织病理学发现。
