Osteochondromas are the most common benign lesions of the bone accounting for 30 to 40% of all benign osseous neoplasms. They are commonly referred to as exostoses. They are common at the metaphyseal end of the long bones. Usually, they are multiple. Flat bones are rarely affected by the osteochondromas. Solitary Osteochondroma of the rib is very uncommon. Osteochondroma affecting the first rib is still further rarer. The first rib osteochondroma may produce serious clinical problems on account of close proximity to vital structures, like, brachial plexus, subclavian vessels. In the present article, a giant sized Osteochondroma arising from the first rib compressing the brachial plexus was successfully removed through transclavicular approach.
