Solid mesenchymal hamartoma of the liver in adult

This paper presents an unusual solid mesenchymal hamartoma of the liver (MH L) in adult. A well defined solid mass in the left lobe of the liver was fo und in a 57-year-old female. Preoperative radiologic examinations demonstra ted solid mass with multifocal calcifications abutting the gallbladder. By light microscopy, the lesion was composed of dense fibrous stroma with hyal inization, bile ducts and thick-walled vessels without hepatocytes. The sol id and hyalinized mesenchymal component would suggest an unusual degenerati ve change representing a burnt-out MHL.
