Co-existing infantile hepatic hemangioma and mesenchymal hamartoma in a neonate

Abstract

Infantile hepatic hemangioma (IHH) and mesenchymal hamartoma (MH) form the first and second most common benign hepatic tumors in children. In this case report, we present a newborn child in whom a growing hepatic mass was discovered at the age of 7 days. She suffered also from anemia, respiratory and renal failure. No signs of heart disease or cutaneous lesions were detected. Alpha-fetoprotein was elevated for her age (3562.2 ng/ml). Imaging studies showed multifocal large cystic lesions associated with heterogeneous small solid lesions with arterial enhancement of the liver. Non-anatomical liver resection was performed initially and synchronous MH and IHH GLUT-1 positive were discovered in the pathological analysis. Segmental IV hepatic resection and later on selective cysts excision were done for persistent hepatic lesion despite medical treatment. After 14 months of beta-blockers treatment, clinical follow-up shows a healthy child with no residual cystic lesions.
