Oncocytoma of the lacrimal sac

Acquired nasolacrimal duct obstruction is often caused by chronic inflammation. Rarely, lacrimal sac tumors are a cause of nasolacrimal duct obstruction. Such tumors include: adenocarcinomas, adenoid cystic carcinomas, squamous cell carcinomas, lymphomas, pleomorphic adenomas and oncocytomas. Oncocytomas of the lacrimal sac are rare with very few cases documented in the recent literature. Oncocytoma is not routinely found in other cutaneous locations, and it may cause diagnostic confusion for those not familiar with it. Therefore, the aim of this article is to report the management of a patient affected by an oncocytoma of the lacrimal sac.
