title: Rare oral cartilaginous choristoma: a case report and review of the literature.
abstract: Cartilaginous choristomas are extraosseous benign tumors. They occur in abnormal sites that usually do not contain chondrocytes. The oral variant of this entity is considered to be very rare, with only 38 cases currently published in the literature. This article presents a case of an oral cartilaginous choristoma lesion. In addition to presenting clinical and histological diagnoses, this article compares the present case to recently reported cases. Special attention was given to analyzing cells of the oral cartilaginous choristoma, which appear as well-differentiated chondrocytes with a pale blue cytoplasm surrounded by a light basophilic stroma and no evidence of malignity. Following surgical excision, the lesion did not recur, which is similar to other reported cases of oral cartilaginous choristomas.
