A Case of Congenital Hepatoblastoma / 대한소아혈액종양학회지

ABSTRACT

Hepatoblastoma is the most common primary malignant hepatic tumor in infancy and childhood. But congenital hepatoblastomas are extremely rare and show distinctive, but important features when compared with tumors diagnosed in children beyond the neonatal age. They have different clinical presentations, higher incidence of pure fetal histology, significant risk for systemic metastasis, and worse outcome. The treatment of congenital hepatoblastoma should be the same as in older children, i.e., primary chemotherapy with delayed resection. We report a case of congenital hepatoblastoma in a 29-day-old boy who was known to have a well-defined ovoid hypoechoic mass at liver demonstrated by fetal sonography.
