Four-year survival of a patient with malignant fibrous histiocytoma of the liver treated with surgery and chemotherapy.

Malignant fibrous histiocytoma of the liver is an extremely rare tumor. A 43-year-old woman was admitted with an enlargement of the abdomen and a feeling of general fatigue. A clinical examination revealed a right liver giant cystic tumor (18.5 × 22 cm). The cystic tumor, which contained a solid component, occupied almost the entire right lobe of the liver, and a solid S4 tumor was also observed. A blood examination revealed severe anemia and mild liver dysfunction. During hospitalization intratumor bleeding occurred. A right lobectomy of the liver and lymph node dissection was performed after transcatheter arterial embolization. Histopathologically, the tumor was diagnosed as a primary storiform-pleomorphic-type malignant fibrous histiocytoma of the liver. One year after the radical operation, the patient developed recurrences in other organs. She received 17 cycles of chemotherapy with etoposide, ifosfamide, and cisplatin. The recurrent tumors decreased in size, but new recurrences in other organs occurred. The patient died of respiratory failure 4 years and 2 months after the initial operation.
