Mesenchymal Hamartoma in a 3-Year-Old Child: Case Report

Liver tumors account for 1 to 4% of solid tumors in children and are mainly represented by hepatoblastoma, hepatocellular carcinoma, and hemangioendothelioma. Cystic mesenchymal hamartoma is a rare benign tumor of the liver in children, accounting for 5 to 8% of primary hepatic tumors. Very few cases have been reported in the literature. We report the case of a 3-year-old girl who presented with abdominal pain. MRI suggested the diagnosis by revealing a large solid-cystic mass in the right lobe of the liver, and histological examination following a CT-guided biopsy confirmed the diagnosis of mesenchymal hamartoma of the right liver. An extended right hepatectomy including segment IVb was performed. The aim of our article is to describe the diagnostic and therapeutic approach to this very rare liver tumor.
