The differential diagnosis is established with osteoarthritic change, chondroblastoma, chondrosarcoma, aneurysmal bone cyst, rhabdomyosarcoma, plasmacytoma, cholesteatoma, intraosseous meningioma, reparative granuloma, tumoral calcium pyrophosphate dihydrate crystal deposition disease, chondroma of the tendon sheath, synovial chondromatosis, tendon sheath fibroma, synovial hemangioma, synovial sarcoma, embryonal rhabdomyosarcoma, giant cell granuloma, brown tumor and malignant fibrous histiocytoma . In the 5 reported cases of TMJ involvement, all patients showed normal serum calcium and phosphate levels. GCTs appear lytic, subarticular, eccentrically located and usually lack a sclerotic rim on radiographs. Unlike intra-articular TC, juxta-articular TC less commonly leads to limitation of mouth opening as joint movement is unaffected. Osteoblastoma involving the TMJ is very rare [ 56 ].
