Osteosarcoma of the Clavicle in an Adolescent Child.

Clavicle is an unusual site for any primary bone tumour, including osteogenic sarcoma. Although a rare site of affection, most clavicular tumours tend to be malignant. We present a case report of osteosarcoma of the clavicle in a twelve-year-old male child who presented with a huge swelling of the left clavicle for the last six months.
