Abstract
- Osseous choristoma rarely occurs, but when it does, the oral cavity of the head and neck lesion is the most common site. It appears as a mass of normal bony structure, consisting of mature osteocytes in an ectopic position. Appearing as a calcification of thyroid mass on radiologic examinations, it could be a benign lesion, chronic inflammation, or carcinoma; the final diagnosis can only be obtained by a pathologic confirmation. Histologically, the lesions show a well-circumscribed mass of vital bone. The treatment of choice is surgical excision. We report a case of osseous choristoma that occurred on the thyroid gland. To our knowledge, such has not been reported previously as a site of osseous choristoma.
