title: [Mesenchymal hamartoma of the liver in an elderly man].
abstract: The mesenchymal hamartoma of the liver is a non frequent benign tumor with a ductal plate malformation, consisting of myxoid mesenchymal tissue and abnormal bile ducts in different proportion. Usually it presents as multiple liver cyst formations without communication with the principal bile duct. They are frequent in children, being rare in adults. The first case was reported by Yamamura et al in 1976, and very few cases are reported in the bibliography. We present the case of an elder 87 year old male who presented a 20 cm mesenchymal hamartoma liver cyst.
