[Aneurismal bone cyst of clavicle: A case report].

Aneurismal bone cyst is a rare tumour. The authors report an exceptional case in its clavicle localization. They review the diagnosis circumstances and treatment modalities of this pathology. The occurrence of the cyst is linked to vascular homodynamic disturbance and its discovery in a post-traumatic context has been assessed by the histology exam. Although numerous therapeutic trials, radical removal versus conservatory methods avoid relapse. Finally, resection of the clavicle leading to few functional consequences should be recommended for the cure of evoluted aneurismal bone cyst.
