Chondromatose de l'articulation temporomandibulaire : étude multicentrique et mise au point à partir de 14 cas

Chondromatosis has a slow evolution and is asymptomatic for a long time. MRI allows to evoke the diagnosis and to locate precisely the osteochondromas. Diagnosis is confirmed by histology that highlights a synovial metaplasia and more or less calcified chondromas. The main differential diagnosis to be eliminated because of prognostic reasons is the synovial chondrosarcoma. Treatment consists in surgical removing of the chondromas. Evolution is usually favorable.
