Choristoma is a term that has been used to describe the growth of some normal tissue in abnormal positions. Osseous choristoma is a well circumscribed benign growth of normal, mature osseous tissue in ectopic sites. This presentation covers a lingual osseous choristoma accidently found during the treatment course of left otitis media. Excision with laser was done and the patient presented with smooth clinical course. No recurrence was noted as the follow up clinic visit. Previous disease related literature was reviewed.
