title: An eyelid tumor caused by a migrated hard contact lens.
abstract: An enlarging eyelid mass was removed and found to be a fibrocollagenous tumor surrounding a hard contact lens which had apparently migrated from the upper fornix, where it had been lost. A review of the literature revealed that formation of such a tumor around a migrated contact lens is unusual but that migration of hard contact lenses through the conjunctiva of the upper fornix is not as rare as is generally believed.
