Mesenchymal hamartoma of the liver (MHL) is a rare benign tumor usually found in childhood, especially during the first two years. MHL is extremely rare in adults. Most reported cases present with a slow growing abdominal mass. It is thought to be a developmental anomaly and consists of bile ducts, hepatocytes and mesenchymal tissue. We report a case of mesenchymal hamartoma of the liver in an adult male with a brief review of the literature.(Korean J Hepatol 2003;9:31-34)
