Primary sarcomas of the liver are rare. A case of primary malignant fibrous histiocytoma of the liver is reported. A 55-year-old male was admitted with epigastric pain. An abdominal computed tomographic scan disclosed a 10cm, low-density area in the left lobe of the liver. Histological examination of the resected tumor showed bundles of spindle cells arranged in a storiform pattern. In some areas, many bizarre giant cells were scattered. Immunohistochemically, tumor cells were positive for alpha 1-antitrypsin and alpha 1-antichymotrypsin, and weakly positive for vimentin. The tumor cells did not express cytokeratin, desmin or alpha fetoprotein.
