Giant cell tumor arising from anterior arc of first rib: a rare presentation

We report a case of Giant Cell Tumor (GCT) arising from anterior are of first rib along with literature review which was treated with excision of rib through its normal margin along with tumor mass. GCT of rib is rare and if found mostly arises from the posterior aspect. However, GCT should be considered as differential diagnosis when bony mass is present in the anterior are of rib. It poses surgical challenge for excision because of the delicate and vital neurovascular structures passing above it between clavicle and first rib.
