Malignant fibrous histiocytoma.

Malignant fibrous histiocytoma (MFH) is a type of histiocytoma and is the most common soft tissue sarcoma of late adult life. However, it is relatively uncommon in the head and neck area. It usually occurs/develops in the lower extremities and in the retroperitonium. This tumour is difficult to distinguish histologically from other sarcomas and carcinomas. Surgery is the only treatment option. Prognosis is fairly poor; recurrence and local metastasis are common. In comparison with MFH of the extremities and the trunk, the 5-year survival rate for cases of this tumour in the head and neck is low. It is important to consider MFH in differential diagnosis of head and neck tumours because of its poor prognosis. We report a rare case of MFH in an 11-year-old girl.
