title: [Sinonasal teratocarcinosarcoma].
abstract: Sinonasal teratocarcinosarcoma is an extremely rare malignant neoplasm presenting with the characteristics of a malignant teratoma and carcinosarcoma. The most common sites of origin of teratocarcinosarcomas are the nasal cavity and paranasal sinuses. The clinical presentation is usually with nasal obstruction and episodes of epistaxis. Teratocarcinosarcomas are aggressive and rapidly growing tumors with a poor prognosis. The incidence of sinonasal teratocarcinomas is higher in men than women. Treatment is primarily surgery, followed by radiotherapy. In this article, we report a 46-year-old male case of sinonasal teratocarcinosarcoma who was admitted with complaints of pain and swelling around the right eye and treated surgically followed by radiotherapy.
