A Case of Osteochondroma of the Tongue / 대한이비인후과학회지

A rare case of the tongue is encountered and we report the case with the literature review on osteoma, chondroma, and osteochondroma of the tongue. The most common oral extraskeletal site is the tongue. The occurrence of osteochondroma in soft tissues of the oral cavity is rather uncommon. They are usually seen on the lateral border and foramen cecum of the tongue. It has been suggested that they arise from metaplastic formation or remnants of branchial arch cartilage. Following surgical removal, recurrence has not been reported. The etiology and pathogenesis remain obscure. The possible causes of this unusual neoplasm are discussed.
