malignant fibrous histiocytoma

Malignant fibrous histiocytoma (MFH) is a type of cancer that is the most common soft tissue sarcoma of late adult life, most commonly occurring between age 50-70. In rare cases MFH does occur in children, but it is usually in a less aggressive form. However, malignant tumors have occurred in children as young as 13. It occurs more often in caucasians than those of African or Asian descent. Its male:female predominance is 2:1.
