Liver mesenchymal hamartoma

Mesenchymal hamartomas are considered to be a developmental anomaly more than true neoplasm. A total of 75% of cases are located in the right lobe of the liver. Histologically MHR arise from the mesenchyma of the portal tract and will have connective tissue, blood vessels, lymphatic spaces, bile ducts and normal hepatocytes (Konez et al. 2001 Cetin et al. 2002). 

Mesenchymal hamartoma of the liver (MHL) is another benign neoplasm in children. Boys are slightly more affected than girls. It is very unusual to find an MHL after 5 years of age. The lesion usually has a good prognosis (Ramirez-Garredo et al. 2003 Yen et al. 2003).
