Nodular myofibroblastic mesenchymal dysplasia of the placenta in association with an unusual bone dysplasia.
This case report describes the recognition of nodular and asymmetric perivascular clusters of myofibrolasts-leiomuscular cells in the stroma of immature chorionic villi associated with a fetus delivered at 26 weeks gestation with a peculiar variation of bone dysplasia syndrome and oligohydramnios. Although myofibroblasts are known to exist at these sites, the finding may represent an unusual mesenchymal dysplasia of the placenta perhaps related to the syndrome.
