Cartilaginous choristoma of tongue - A case report and review

Choristoma (aberrant rest or heterotopic tissue) is defined as a histologically normal tissue proliferation, which is not normally found in the anatomic site of proliferation. Choristoma with a proliferation of chondroid tissue is known as cartilaginous choristoma. Clinically, they present as a painless firm nodule and may produce local dysfunction. They occur most frequently in the tongue and less commonly in other sites, such as buccal mucosa, soft palate and gingiva. We report a 35 years female patient with pedunculated globular growth over the left lateral border of the tongue, resembling papilloma but histopathological analysis of the excised specimen revealed to be cartilaginous choristoma.
