Hence clinicopathological and radiological correlation is very important. On the other hand, morphological variations can occur in the same group of lesions and various other conditions enter in the differential diagnosis. Foci of hyaline cartilage when present, may lead to a wrong diagnosis of cartilaginous tumour. The transition of normal to abnormal bone is often abrupt in fibrous dysplasia and is a useful diagnostic clue on radiological examination. Further, association of fibrous dysplasia with primary bone sarcoma has been reported.
Fibrous dysplasia needs surgical treatment, curettement being adequate for long bones.
Resection is rarely indicated as in rib involvement. In a maxilla, partial removal of the lesion is sufficient to minimise the deformity. Benign fibro-osseous lesions of the jaws. Zavaleta A. Osteoma, ossifying fibroma and fibrous dysplasia of facial and cranial bones. Benign fibro-osseous lesions of the mandible and maxilla.
