Fibrous tumors of bone.

Benign and malignant fibrous tumors of bone are some of the most common tumors encountered by the orthopedic surgeon. Fibrous dysplasia, fibrous cortical defect, non-ossifying fibroma, benign fibrous histiocytoma and osteofibrous dysplasia are benign tumors best treated conservatively or by intralesional/marginal excision. Desmoplastic fibromas are locally aggressive and require a wide margin for surgical cure. Malignant fibrous histiocytoma and fibrosarcoma of bone are malignant bone tumors and must be treated with wide/radical margins and for malignant fibrous histiocytoma adjunctive chemotherapy.
