Osteochondroma of the Atlas Presenting as an Oropharyngeal Mass / 대한이비인후과학회지

ABSTRACT

Osteochondroma, also known as osteocartilaginous exostosis, or just exostosis, is the most common benign bone tumor. Most of osteochondromas are solitary lesions and affect long bones; however, about 12% of osteochondromas are multiple lesions with the autosomal dominant inheritance. Only 1~4% of solitary osteochondromas originate in the spine. Symptoms vary depending on its location. We experienced a case of osteochondroma of the atlas presenting as an oropharyngeal mass. We report the case with a review of literatures.
