title: Sinonasal teratocarcinosarcoma-A case report.
abstract: Sinonasal teratocarcinosarcoma is a very rare tumor of ambiguous origin. Detailed examination of the biopsy material is essential for diagnosis. It is a very aggressive tumor with a five-year survival rate of 45%. Surgery with radiotherapy has been shown to be effective. We report a case of a 38-year old Indian gentleman with left nasoethmoidal mass eroding the cribriform plate with intracranial extension. Subtotal endoscopic excision of the mass revealed features of a sinonasal teratocarcinosarcoma. Immunohistochemistry confirmed the same. The patient was subsequently treated with radiotherapy. The clinical features, histopathological and immunohistochemistry findings and management of sinonasal teratocarcinosarcoma are discussed.
