Malignant fibrous histiocytoma of the liver--a case report

A case of surgically confirmed primary malignant fibrous histiocytoma of the liver is presented. A 35-year-old man was admitted to hospital with an epigastric mass. No abnormal laboratory findings, including tumor markers, were detected. Ultrasound and computed tomography showed the main tumor in the left lateral segment and a daughter nodule in the posterior segment of the liver. Arteriography demonstrated a slightly hypervascular mass in the left lateral segment. Histological examination of the resected tumor showed bundles of spindle cells with a focal storiform pattern, which were intermingled with bizarre giant cells, therefore a diagnosis of malignant fibrous histiocytoma was made.
