Hepatic mesenchymal hamartoma is a rare benign tumour in children. It is often 
large and centrally located in the liver at diagnosis, making surgical resection 
difficult; thus non-radical resection has been proposed in the past as 
acceptable management. However, a literature survey and a case with recurrence 
associated with cytogenetic anomalies suggest that radical liver surgery 
(resection with a margin of normal liver parenchyma, as for malignant tumour) 
should be recommended for mesenchymal hamartoma.
