Hepatic mesenchymal hamartoma

: Hepatic mesenchymal hamartoma (HMH) is a rare liver tumour in childhood. It is believed to be a benign tumour with a good prognosis if the tumour is excised. Only a few cases with local relapse or metastasis have been reported. We reviewed 134 patients with space‐occupying liver lesions, from January 1990 to December 1999, and four patients with HMH were found. Abdominal mass and/or distension were the common initial presentations. Three of our four cases were diagnosed in the first year of life. The liver function tests and tumour markers were non‐specific. Case 1 underwent tumour enucleation and another three cases underwent tumour excision. One patient died. No tumour recurrence was noted in the surviving patients.
