    (Murcia: F. Hernández, 2007) Ye, M-F.; Zheng, S.; Xu, J.H.; Chen, L-R.
    Primary malignant fibrous histiocytoma (MFH) of the liver remains extremely rare with only several cases having been reported in literature. We report a case of hepatic MFH in a 53-year-old man who presented with upper abdominal pain, and weight loss for one month. Ultrasound and computed tomography (CT) scan showed a large mass with fine tumor vessels over the left lobe of the liver. Histopathological findings indicated a mesenchymal tumor consisting of spindle cells in storiform pattern intermingled with histiocytelike cells and giant cells. Immunohistochemically, most tumor cells expressed vimentin, alpha-1 antichymotrypsin, alpha-1 antitrypsin and CD68. Morphological and immunohistochemical findings support that the tumor should be classified as a primary malignant fibrous histiocytoma. The literatures is briefly reviewed.
