Abstract

Mesenchymal hamartoma of the liver (MHL) is a rare benign tumor in early childhood. It makes up about 6% to 8% of all pediatric hepatic tumors, and is mostly found during the first two years of life. Fine needle aspiration or needle biopsy plays an important role in the diagnosis of MHL, but it may sometimes be inadequate to exclude common malignant hepatic tumors such as hepatoblastoma. We describe a case of MHL diagnosed by an ultrasound-guided percutaneous needle biopsy in a 16-month-old girl who presented with abdominal distension. Abdominal CT scan revealed a large, mixed solid and multicystic tumor in the right lobe of the liver. Microscopic finding showed a large amount of myxoid mesenchymal stroma and abnormal bile ducts, which was compatible with MHL. After the right lobectomy, the patient remains well on the follow-up without any recurrence of MHL.
