Multiple hepatic mesenchymal hamartomas in a premature associated with placental mesenchymal dysplasia

Abstract

Placental mesenchymal dysplasia (PMD) is an uncommon disorder that has to be differentiated histologically from a partial mole. In contrast to a hydatitiform mole, PMD can coexist with a viable fetus. Placental mesenchymal dysplasia is characterized by placentomegaly and dilatation of the chorionic vessels. In our case, multiple hepatic mesenchymal hamartomas in a preterm were associated with PMD. This association is an extremely rare anomaly. Mesenchymal hamartomas occur in 5% of all primary liver tumors in children and are generally benign lesions.
