Malignant Epignathus with Intra Cranial Extension: A Very Unusual Case
نویسندگان
چکیده
Epignathus or oropharyngeal teratomas are extremely rare congenital neoplasms that arise from the oral cavity or pharynx. Teratomas commonly occur in sacrococcygeal region. However, less than 5% occur in the head and neck. Malignant teratomas account 5%-30% of all teratomas. We present an unusual case of immatureoropharyngeal teratoma that arises from sphenoid with intracranial extension, in a 22 weeks female fetus. There are many types of head and neck tumors, so we should always keep in mind epignathus in the differential diagnosis of head and neck tumors.
