Introduction: The clavicle is a very rare site for primary bone tumours, and Giant cell tumours of the clavicle are even rarer. Very few cases have been reported in the literature.
Method: The authors report a rare presentation of intrathoracic extension of a giant cell tumour of the medial end of the clavicle, in an 18-year-old female. The patient had painful swelling at the sternal end of the clavicle associated with a painful shoulder range of motion. Complete resection of the mass was done, preserving the lateral half of the clavicle.
Result and discussion: At a 3-year follow-up, the patient has a good clinical outcome with no signs of recurrence. Being a very rare entity, no clear guidelines are available for the management of GCT of Clavicle. Adequate resection of the tumour mass remains the mainstay of treatment and has shown promising results. Denosumab has been proved to be effective in some studies, but the high cost of treatment is a major limitation in the Indian scenario.
Conclusion: Resection of the tumour mass with partial cleidectomy provided good results in this patient.
