title: Orbital chondroma.
abstract: A 9-year-old boy was referred for increasing ptosis in the left eye. CT and MRI revealed a well-circumscribed mass in the superonasal orbit. An anterior orbitotomy was performed and the mass was excised in toto. Pathologic evaluation revealed a pure chondroma. Chondroma is an uncommon tumor that may rarely present as an orbital mass.
