Malignant fibrous histiocytoma (MFH) of bone is a malignant primary bone tumour that is being increasingly recognised, as more details emerge in the literature regarding its natural history and precise (although sometimes diverse) histological appearance. When the whole bulk of a malignant bone tumour fits the criteria laid down, the designation of MFH seems appropriate. Seven cases of MFH of bone were encountered from a total of 220 primary malignant bone tumours in our files over a 4-year period. The metaphyses of long bones were the most common sites harbouring the tumour, and a wide age range was represented. Amputation was the treatment of choice in all cases. The relevant literature is reviewed.
