Summary

By definition, choristomas are normal tissues found in anomalous topography. The cartilaginous features of these lesions are rare in the soft tissues of the oral cavity. The majority of cartilaginous choristomas of the tongue—the primary site of emergence of the oropharynx—are associated with adipose, fibrous or bone tissues—apart from that, only a few of these were confirmed by an immunohistochemical study. The neoplasm exclusively composed of chondromatous tissue is extremely rare in the tongue. This paper reports the clinical, surgical and pathological characteristics of a cartilaginous choristoma of the tongue diagnosed in a 64-year-old woman.
