Abstract

Adenoid cystic carcinoma is more common in minor salivary glands, uncommon in parotid gland and rare in paranasal sinuses. These are more aggressive and fatal. Such tumors of the accessory nasal sinuses causing proptosis have been reported so rarely in ophthalmic literature. An adult aged 31 years presented with proptosis of right eye, nasal obstruction and bleeding from right nose. CT scan showed soft tissue attenuation mass with destruction of bony structures and extension to right orbit. Biopsy was done through trans nasal route. A histological diagnosis of Adenoid cystic carcinoma of ethmoid sinus was made.
