Aneurysmal bone cyst of the ethmoid presenting with proptosis and epiphora.

An aneurysmal bone cyst of ethmoid is a rare and distinct clinicopathologic entity. The diagnosis is important in this localization because it requires multidisciplinary approach in its management. We report a case of a 14-year-old woman presenting to our clinic with the complaint of epiphora and proptosis in the right eye, which were the symptomatic findings of aneurysmal bone cyst of ethmoid.
