Epignathus is a rare congenital orofacial teratoma. Teratomas are tumors that originate from all three germs cell layers. Tumor size is an important prognostic factor, and we describe the case of massive epignathus identified by sonography at 25 weeks. Our case was a 35-year-old pregnant woman that was subjected to a routine ultrasound at 25 weeks of gestation, and epignathus was diagnosed. Labor pain started in the 28th week of the pregnancy, so the dead fetus was aborted, and curettage was conducted. A pathologic sample was sent to the laboratory, and benign teratoma was diagnosed. Because fetal epignathus has a wide range of outcomes, early prenatal diagnosis is essential for optimal management.
