Abstract

PURPOSE
To report the symmetric masses developed in both eyes, which were diagnosed with bilateral osseous choristoma and surgically excised. METHODS: A 6-year-old female was noted by her parents to have a mass under the conjunctiva of her left eye. The mass was white and firmly attached to the globe. The same lesion was present in the right eye. CT scan showed that the masses were high bone-density and did not invade the sclera deeply. Therefore, excisional biopsy of the lesions were performed. RESULTS: Histopathologic examination showed that the masses were episcleral osseous choristoma. There was no complication of recurrence or adhesion after surgery. CONCLUSIONS: In case of a hard mass under the conjunctiva, which is diagnosed with osseous choristoma by CT scanning, it is helpful to determine the accurate location and adhesion of the massfor successful surgery.
