Fetal hepatic mesenchymal hamartoma: a case report.

Hepatic tumors accounted 5% of congenital neoplasms. Mesenchymal hamartoma of the liver is a rare benign childhood tumor, whose definitive diagnosis during the fetal period remains difficult, despite advances in antenatal imaging. In this paper, we report a case of hepatic mesenchymal hamartoma diagnosed prenatally with ultrasound scan showing a multicystic mass in the left upper abdomen accompanying polyhydramnios and complicated by a preterm labor. The newborn died on the first day of life due to respiratory distress and neonatal jaundice. The diagnosis was confirmed histologically post-delivery.
