Bone formation in association with a limbal dermoid

J. M. Weinstein, P. E. Romano and R. B. O'Grady

A healthy female infant was born with a unilateral limbal dermoid. When the lesion was surgically excised, a plaque of bone was found under the scleral portion of the lesion. The occurrence of bone in ocular dermoinds is extremely uncommon and, to our knowledge, has been reported only twice in dermoids that occur in epibulbar locations away from the limbus.
