We present a case of a fetal pharyngeal teratoma, which was diagnosed at 21 weeks' gestation. At the time of examination, a mass of mixed echogenicity was detected that protruded through the mouth. During a second examination 3 weeks later, the tumor had increased in size, and a severe polyhydramnios had developed. Intrauterine death of the fetus was detected at 27 weeks' gestation. Labor was induced with misoprostol, and a 1,015-g stillborn female neonate was delivered. Postmortem examination confirmed the diagnosis of a pharyngeal teratoma.
