Case 100 (HPC:100) : Fibrous dysplasia of bones
Definition: Benign and malignant fibrous tumors of bone are some of the most common tumors encountered by the orthopedic surgeon.
Types
reactive or post-traumatic tumors of bone
- periosteal "desmoid" tumors
- non-ossifying fibroma
- fibrous cortical defect
- fibrous metaphyseal defect
- benign fibrous histiocytoma
benign fibrous tumors of bones
- fibrous dysplasia (fibro-osseous dysplasia, fibro-osseous lesion)
- osteofibrous dysplasia (differentiated adamantinoma)
- desmoplastic fibroma of bone
- desmoid fibromatosis of bone
- liposclerosing myxofibrous tumor
malignant fibrous bone tumors
- malignant fibrous histiocytoma
- fibrosarcoma of bone
- adamantinoma of long bones
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.
