SummaryBy 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. BACKGROUND

“…This theory is particularly attractive for explaining lesions located on the lateral border, ventral surface or tip of the tongue, especially in an older age group [17,18,21,22,28,32,33]. Some papers have reported that traumatic cartilaginous metaplasia is also seen within flabby edentulous alveolar ridges in response to mechanical irritation caused by ill-fitting dentures [46,47].…”

Soft tissue chondroma of the palate is a rare lesion. We report a rare case of soft tissue chondroma of the hard palate with a review of the literature. A 59-year-old man was referred to our department because of a symptomatic mass on the median anterior margin of the hard palate of 4 year's duration.The lesion was approximately 15×10×8 mm in size and pedunculated. The lesion was excised under local anesthesia, and the pathological diagnosis was soft tissue chondroma. The histopathological findings suggested that the heterotopic formation of cartilage was caused by the metaplastic change of mesenchymal cells into chondrocytes. Postoperative wound healing has been uneventful, with no sign of recurrence during 2 years after surgery.

“…Within the oral cavity, endogenous elements that might result in hamartomatous proliferations include smooth muscle (2, 3), vessels (4), nerves, lymphatics, skeletal muscle (5), fat (6), salivary tissue (7), and epithelium (8). Choristomatous elements in the oral cavity might include bone (9), cartilage (10), glial tissue (11, 12), and skin appendages (13). Glial tissue hamartomas were also described in the oral cavity (14) but these should have probably been better diagnosed as choristoma, because glial tissue is not a normal component of oral mucosa.…”
