This is from a 76-year-old male with a fungating maxillary antral mass that extends into the nasal cavity. Sinonasal teratoid carcinosarcoma was first described in 1984 and since then 60 cases have been reported. I have had the opportunity to encounter four cases locally. the first one in 1995. https://allfixelectricales.shop/product-category/immersion-element/
