REYNA-VILLASMIL, Eduardo; TORRES-CEPEDA, Duly  and  RONDON-TAPIA, Martha. Prenatal diagnosis of placental mesenchymal dysplasia. Rev. peru. ginecol. obstet. [online]. 2021, vol.67, n.1, 00012. ISSN 2304-5132.  http://dx.doi.org/10.31403/rpgo.v67i2309.

Placental mesenchymal dysplasia is a rare and benign placental abnormality. It is characterized by placentomegaly with multiple cystic lesions of the villous tree and vascular abnormalities along with increased maternal serum alpha-fetoprotein concentrations. It is an unknown clinical entity and can be confused with gestational trophoblastic disease due to the similar ultrasound findings in both entities; but the management and the perinatal outcome are different. It should be included in the differential diagnosis of ultrasound findings showing a normal-appearing fetus and a placenta with cystic lesions. However, placental mesenchymal dysplasia is associated with complications such as intrauterine growth restriction and intrauterine fetal death. Due to the high number of complications and associated pathologies, it is necessary to increase ultrasound evaluations to reduce fetal morbidity and mortality. A case of prenatal diagnosis of placental mesenchymal dysplasia with normal fetus is presented.
