A case of primary malignant fibrous histiocytoma of the pancreas with liver metastasis

Malignant fibrous histiocytoma （MFH） is one of most common types of soft-tissue sarcoma. However, it accounts for less than 1% of all human cancer types. In addition, primary MFH of the pancreas is very rare. Herein, we report of a 37-year-old man who presented with a pancreatic mass and did not show any specific symptoms. Pre-contrast computed tomography （CT） showed a heterogeneous, liquid-filled necrotic mass in the uncinate lobe of the pancreas. Contrast-enhanced CT showed a mild enhancement of solid components and the pancreaticoduodenal artery across the mass. The patient underwent a pancreatico- duodenectomy, ethanol ablation of the liver lesions, and chemotherapy with 4 cycles of ifosfamide and doxorubicin. The tumor recurred in the liver, but not in the pancreas, after 8 months.
