title: Lacrimal drainage system inflammatory masses from retained silicone tubing.
abstract: In two cases studied we found inflammatory masses of the lacrimal system associated with retained silicone material. We saw the first patient two years after a failed dacryocystorhinostomy. A mass of the superior punctum mimicking a lacrimal sac or canalicular neoplasm consisted of chronic granulomatous inflammation centered around retained silicone tubing. In the second patient, a foreign body giant cell inflammatory reaction occurred in the lacrimal sac in which there were retained knots of silicone tubing. We believed the inflammation in these patients to be caused by the knots and the cut ends of the silicone tubing present in the lacrimal drainage system.
