An oropharyngeal teratoma is a rare malformation. It is also known as epignathus. It is composed of all three germinal layer derived cells. Only few cases are reported. We present a case of large teratoma that was arising from the tongue in a newborn. Total surgical excision was performed and histological examination showed mature teratoma.

| Introduction|| |
Teratoma was defined by Weaver et al. as a tumor consisting of multiple tissues that are not indigenous to their site of origin. It is a tumor composed of multiple tissues foreign to the normal organ from which it arises. Most common sites are the sacrococcygeal, anterior mediastinum, testicle, ovary, or retroperitoneum. Teratoma of the head and neck is rare, and only 10% of teratoma find in this area. Nasopharynx and cervical region are the most common sites. Epignathus describes as a tumor in the oropharyngeal region, with an incidence of one in 35,000–200,000 live births.
| Case Report|| |
Parent of a 2.3-kg term female newborn presented to us with the complaints of respiratory difficulty and large irregular oral mass with bleeding. The baby was delivered by cesarean section to a 23-year mother who had a regular antenatal examination. In antenatal ultrasound, teratoma was detected. After delivery, the newborn had respiratory difficulty with bleeding from a large irregular mass arising from the tongue, protruded anteriorly [Figure 1]a. The patient had chest indrawing and tachypnea. The patient was intubated immediately and was prepared for the surgery. Complete resection of tumor was performed [Figure 1]b. The patient was shifted to the neonatal intensive care unit on ventilator after the surgery. The patient was in shock. Postoperative recovery was not uneventful, and the baby expired after 1 day because of hypovolemic shock.
| Discussion|| |
Teratoma contains all three germ cell layers (ectoderm, mesoderm, and endoderm). Histologically, they may be mature, immature, or malignant. They may arise from different sites in the body, the most common is sacrococcygeal (accounts for approximately 40% of total cases). Less than 5% occur in the head and neck. Epignathus is a teratoma that arises from the oropharynx. When large, they distort the facial anatomy and cause respiratory embarrassment at birth. Our case was noted to have oral mass causing respiratory difficulty.
Teratomas are more common in female. When present during early childhood, they are usually benign. As in most reported cases, our patient was female, and the tumor was benign.
Teratoma may be diagnosed antenatally on ultrasound or magnetic resonance, which permits early multidisciplinary management. The diagnosis was confirmed by polyhydramnios. The differential diagnosis is limited but includes hamartoma, dermoid cyst, and heterotopic gastrointestinal cyst. Teeth within the mass confirm teratoma. The fetus with teratoma is also at risk of high-output cardiac failure, placentomegaly, and hydrops with subsequent fetal demise secondary to arteriovenous shunting through the tumor or chronic fetal anemia due to hemorrhage within the tumor.
Resection is the treatment of choice, as there may be a small chance of malignant transformation, the longer they are left. If antenatal diagnosis is made, two treatment procedures may be used: ex utero intrapartum treatment (EXIT) procedures and operation on placental support (OOPS).
In the EXIT procedure, after a low transverse uterine incision, the head and at least one hand of the fetus are delivered. In the OOPS procedure, first, the airway is secured by endotracheal intubation or tracheostomy; later, the baby is completely delivered and the umbilical cord is clamped. In our case, the patient was delivered outside from our center; so, EXIT procedure was not possible.
Kolekar et al. reported a case of oral teratoma in a newborn with respiratory difficulty. The neonate's prognosis worsens as the size of tumor increases. Mortality in oral teratoma is high in the absence of well-prepared resuscitation team or meticulous delivery planning to secure the airway. Das et al. reported a case of nasopharyngeal teratoma in a newborn causing airway obstruction. In our case, tumor detected antenatal and cesarean section was planned because of large size but due to handling during delivery bleeding started. The patient was intubated immediately and operated in an emergency department within 2 h after the delivery. Hence, it is important to handle these teratomas with care during delivery. Other causes of death in oral teratoma are respiratory tract obstruction and feeding difficulties. Causes of bleeding in teratoma are disseminated intravascular coagulation and thrombocytopenia.
| Conclusion|| |
This report emphasizes on antenatal detection of teratoma and delivery by the EXIT procedure. Large oral teratoma should be handled gently.
