title: Epipalpebral conjunctival osseous choristoma.
abstract: Two cases of osseous choristoma are described. One of the tumours was found in the conjunctiva of the right lower lid, an apparently unique location. The other more typical epibulbar tumour was found in the superior temporal quadrant of the episclera between the lateral and superior rectus muscles. In both instances the tumour was suspected of being a dermoid.
