Giant Cell Tumour of the Sternum: a Case Report and Review of the Literature.

Primary giant cell tumour (GCT) originating from the sternum is rare. We report a case of painless slow growing sternal GCT in a 28-year-old man. Computed tomography showed a destructive lesion of the sternal body. Total sternectomy and reconstruction with polypropylene mesh and methyl methacrylate were performed. The tumour was 16 × 13 × 12 cm in size, and the histopathological examination confirmed GCT. Surgical resection of sternal GCT and appropriate reconstruction are important to minimize local recurrence and maintain good functional and aesthetic outcome.
