[Aneurysmal bone cyst of the clavicle: about a case]. / Kyste anévrismal osseux de la clavicule: à propos d'un cas.

Anevrysmal bone cyst is an aggressive, destructive but benign lesion in the long bones, spine or basin, affecting mainly children and young adults. However, it is a very rare tumor. We here report the case of a 8-year old boy with a very rare localization of anevrysmal cyst in the clavicle, initially presenting with pathologic bone fracture, that is a benign cystic lesion. The child underwent complete radical resection of the cyst located at the level of the right clavicle, followed by anatomopathological examination of surgical specimen which confirmed the diagnosis. Patient's evolution was marked by the absence of recurrences and by good radiologic bone remodeling. Radical cyst resection seems to avoid recidivism. This study aims to update the current understanding of this rare orthopaedic condition by comparing our results with those reported in the world literature.

[Scapular involvement: uncommon presentation of childhood tuberculosis]. / Tuberculose de l'omoplate chez l'enfant: à propos d'une localisation exceptionnelle.

Tuberculosis of bone is an infectious disease which represents a major public health problem in developing countries where it is endemic. Osteoarticular involvement accounts for 1-5% of all cases of tuberculosis, shoulder involvement is very rare and accounts for 1-2% of all cases of osteoarticular tuberculosis. We here report an uncommon case of TB infection involving the scapula, reaching the scapular body. Tuberculosis is still an important differential diagnosis of rare or chronic bone diseases, including tumors. In our study anatomopathological examination led to the diagnosis.
