[Cartilaginous tumours].

Cartilaginous tumours are rare and often incidentally discovered on imaging. They can also be responsible for osteoarticular symptoms (pain, joint stiffness, deformity or fracture) and will require a clinical, radiological and a histopathological assessment. Depending on the lesion, the management may consist of observation or a complex surgical procedure that will take place after a multidisciplinary discussion including the radiologist, the pathologist and the orthopaedic surgeon. The discovery of such cartilage tumours often induces a significant dose of anxiety in the affected patients. A better knowledge of these lesions by the family practitioner and the orthopaedic surgeon therefore seems very useful to provide optimal care before referring the patient to a specialized centre.
