In the present case incisional biopsy was carried out twice to eliminate possible malignancy and differentiate the lesion from osteofibrous dysplasia. The affected side of mandible was operated with the treatment protocol through preserving the mental nerve in order to minimize the risk of intraoperative complications including paresthesia and bleeding from neurovascular structures.
These lesions include solitary bone cyst, aneurysmal bone cysts, osteofibrous dysplasia, myositis ossificans, brown tumour of hyperparathyroidism, and giant-cell granuloma.
Based on the radiographs, the differential diagnosis may include intramedullary osteosarcoma, osteofibrous dysplasia, adamantinoma, and solitary bone cysts.
The other top differential diagnoses to be considered based on histology and location are osteofibrous dysplasia and adamantinoma-like Ewing sarcoma.
The differential diagnosis of fibrous dysplasia includes lesions like Paget's disease, Non ossifying fibroma, Simple bone cyst, Enchondroma, Adamantinoma, Aneurysmal bone cyst, Osteofibrous dysplasia, Diffuse sclerosing osteomyelitis and Giant cell tumour.
