Abstract
Malignant sinonasal carcinomas constitute <1% of all cancers with annual incidence of 3.5 per ten thousand population and of these, 15-20% are non-keratinizing with a male preponderance. We report a case of 56 year male with history of nasal obstruction and discharge. CECT showed large, expansile mass predominantly in left nasal cavity with destruction of adjacent sinuses. A biopsy was taken which revealed Non-keratinizing carcinoma (transitional type).Rarity of this case and multiple confusing nomenclatures prompted us to report this case.
Keywords: Non keratinizing carcinoma, transitional cell cancer, sinonasal cancer.
