Hemoperitoneum as the presenting sign of hepatoblastoma in a newborn

Hepatoblastoma is rarely diagnosed in the neonatal period. We report a neonate in whom massive hemoperitoneum was the presenting sign of hepatoblastoma: tumor injury during vaginal delivery resulted in tumor spread and hemoperitoneum leading to conservative surgical treatment. The authors propose that in cases where intrauterine ultrasonographic findings suggest a hepatic mass, cesarean section should be considered in order to improve the prognosis in cases of congenital hepatoblastoma.
