Malignant fibrous histiocytoma of the pericranium: case report.

Malignant fibrous histiocytoma only infrequently arises from structures of the head and neck. When it does, it most often originates in facial structures, particularly the maxilla. This case report details a malignant fibrous histiocytoma arising from the pericranium, and presenting clinically as a large indurated frontal calvarial mass. A CT scan showed its origin to be from the pericranium and demonstrated its intracranial extension. Radical excision presented a surgical challenge because of the extensiveness of the lesion. Yet, combined with post-operative teletherapy, a favourable outcome was obtained.
