Osteochondromas are characteristically benign cartilaginous neoplasms and are one of the most frequent benign tumors, usually targeting the axial skeleton. We came across an unusual presentation of this lesion, whereby the location of the osteochondroma is unique to the literature, and the morphological features are classified as rare. This study reviewed a case of a resected osteochondroma in a clavicle, which reoccurred a year later as chondrosarcoma. The decision was made to resect the malignant transformation. Due to the critical location of the lesion, the clavicle was left in a position where it was suspended. To protect the anatomical surroundings from the suspended clavicle, a pectoralis major flap was sutured to the sternocleidomastoid muscle. The patient has been symptom free for the past 2 years, and functional abilities have been preserved.
