Choristomas are proliferation of histologically normal tissue in an ectopic location. Cartilaginous choristoma of oral soft tissue are rare lesion. They occur most frequently in the tongue and less commonly in other sites such as buccal mucosa, soft palate and gingiva. It is suggested that intraoral choristoma are developmental lesion. Definite diagnosis is obtained only after histopathologic examination. The treatment of choice is surgical excision. We present two cases of cartilaginous choristoma, one on lateral border and another'on dorsum of tongue along with review of literature.
