Prenatal Diagnosis of Orofacial and Neck Tumors

The prenatal finding of a fetal head and neck tumor poses a challenge because they are very rare lesions that are difficult to evaluate due to their frequent large dimensions, heterogeneous features, and irregular extension into adjacent organs. Formation of a differential diagnosis of facial mass in the fetus is essential in guiding the prenatal counseling of the parents and in guiding the prenatal and/or postnatal management. They can be classified according to the site of origin and histology (Tables 5.1 and 5.2).
