Oropharyngeal teratomas: a clinicopathologic study of four cases.

Oropharyngeal teratomas (OPT) represent an uncommon congenital tumor with significant morbidity and mortality. Optimal management requires prenatal diagnosis. The clinicopathologic features of four OPT (one stillbirth, two livebirths, and one therapeutic abortion) are reviewed and compared with cases previously reported in the literature. Diagnosis, management, clinical outcome, and the natural history of the entity are discussed.
