Cervical teratoma is very rare. We are presenting here a case of cervical immature teratoma in a neonate with review of literature. A 17-day-old male baby with huge cervical teratoma and oral extension presented to us with feeding difficulties. We completely excised the tumor. The infant was discharged after 7 days with mild facial palsy. Uneventful recovery followed without recurrence. Histopathology suggested immature cystic teratoma. There was huge cervical teratoma with oral extension in the neonate. It was located at the cervical region which is very rare, and it was present in the male baby. We completely excised the tumor with mild facial palsy without recurrence. It should be kept in mind in case of neck swelling in a neonate. Cervical teratoma is a rare variety.

| Introduction|| |
Classically, teratoma is composed of tissues from the three embryonic germ layers: ectoderm, mesoderm, and endoderm. Most commonly found in the sacrococcygeal region, these tumors are rare in the neck region. The cervical area is exceptionally affected. The symptoms are mostly attributed to the mass effect of these lesions, making the cervical tumors potentially lethal. Here, in the case report, we are presenting a rare case of huge cervical cystic teratoma with oral extension in a neonate.
| Case Report|| |
A 17-day-old male baby was referred to us with a huge cervical mass detected at birth. Baby was asymptomatic except the neck swelling with some feeding difficulty. On local examination, there was a huge solitary left neck mass extending in the oral cavity, which was irregular, with a size of about 8 cm and having cystic-to-firm consistency with moderate mobility and no skin changes [Figure 1]. Blood investigations were within normal limits. Tumor markers (AFP and bHCG) were in normal range. X-ray neck lateral view suggested calcification in the soft-tissue shadow [Figure 2]. Computed tomography (CT) scan revealed tumoral calcifications and suggested mature cystic teratoma [Figure 3]. The infant underwent surgical excision. Through a left cervical incision, the tumor was completely excised [Figure 4]. The infant was discharged after 7 days with mild facial palsy. Uneventful recovery followed without recurrence. Histopathology suggested immature cystic teratoma.
| Discussion|| |
Teratomas originate from aberrant germ cells at the 4th or 5th week of gestation. These ectopic germ cells undergo proliferation and differentiate in mature (mature teratoma) or fetal (immature teratoma) tissue, depending on the amount of immature elements, most often neuroepithelium.
Teratomas are known to occur anywhere in the body, the most common location being the sacral region. Cervical presentation constitutes 1.6%–9.3% of all pediatric teratomas, roughly equating to 1/40,000 births. They predominate in females (3/4 of the cases). In our case, it was present in the male baby.
Mature teratomas consist of well- differentiated tissues and may be pure or have a histologic component of a mixed germ cell neoplasm. Immaturity does not equate to malignancy, as was previously thought, and <5% of congenital cervical teratomas are malignant.,
Immature teratomas may be a component of a malignant germ cell tumor of mixed histology. The malignant component of mixed histology tumors that contain teratoma is usually of germ cell origin (yolk sac tumor, germinoma, embryonal carcinoma, or choriocarcinoma) and only rarely of somatic origin.
Clinically, a cervical teratoma appears as a large single mass, although multiple lesions may occur. Airway obstruction is the main complication and is related to the size and site of the lesion, occurring in 80% to 100% of cases. Peripartum mortality is often related to difficulty in establishing an airway after delivery.
The diagnosis can be made in utero on ultrasonography in pregnancy (15–16 weeks). The antenatal diagnosis of large congenital cervical teratomas allows for planned intervention by experienced personnel. Ultrasonography three-dimensional and magnetic resonance imaging (MRI) may enhance the accuracy of the antenatal diagnosis and may help in the selection of newborns requiring early treatment.
if the mass present after birth then ultrasonography, CT, and MRI are of primary importance for determining the extension, involvement of adjacent structures, and helps in planning surgery. Complete excision should be done in all cases. The procedure must not be delayed because these lesions, although benign, may grow quickly.
If prenatal diagnosis is made, two procedures may be used: 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. The rest of the body along with the umbilical cord and the placenta remain in utero. This allows examination of the airway. In the OOPS procedure, the baby is completely delivered, and the umbilical cord is clamped only after securing the airway with endotracheal intubation, using a laryngoscope or rigid bronchoscope or tracheostomy.
Regarding the treatment of immature teratomas, Marina et al. found in a retrospective study of 73 children with extracranial immature teratomas that >85% of patients can be effectively treated with surgical resection alone and close observation.
With good preoperative planning and complete surgical excision, there is no recurrence and few complications. A regular and long-term follow-up is necessary to detect early recurrences. Follow-up is based on clinical examination and MRI, especially in case of incomplete excision. A trimestrial alpha-fetoprotein quantification is recommended by some authors., The recurrence can occur in <10% of operated patients and can be treated with further surgery or chemotherapy.,
| Conclusion|| |
Teratomas are rare tumors derived from all three germ cell layers affecting the neck in 3% of all cases. An early complete surgical approach to congenital cervical teratomas allows good results, with low rates of complication and recurrence.
