A case report of nasopharyngeal teratoma with a cleft palate and an inguinal hernia

Success in Emergency Treatment of Neonatal Giant Teratoma with Cleft Palate: A Case Report

Neonatal teratoma, a common congenital malformation, rarely occurs in the head and neck region, especially not within the oral cavity. This report presents a case of neonatal giant teratoma in the oral cavity and oropharynx along with cleft palate, which caused postnatal airway obstruction and respiratory distress and required postnatal resection in a female newborn. After the delivery and routine neonatal examination, the anesthesiologist conducted orotracheal intubation to establish the airway, and tumor resection was immediately done under local anesthesia. The optimal treatment of neonatal teratoma is exclusive emergent surgery. Immediate postnatal resection is necessary to prevent airway obstruction.

Prenatal Diagnosis and Immediate Successful Management of Isolated Fetal Epignathus

Epignathus or enigmatic teratoma is rare congenital tumor, arising from the sphenoid region of the palate or pharynx. A 30-year-old pregnant woman presented at 34 weeks + 2 days’ gestation with a well-defined solid mass measuring 6.47 cm × 5.7 cm arising from the fetal oral cavity. The color flow mapping showed that the mass was well vascularized, especially in its center, and its blood supply was originated from the fetal oral cavity. The newborn has no chromosomal abnormalities or other associated anomalies and/or intracranial extension immediately and successfully managed after delivery to highlight the importance of prenatal diagnosis and the importance of multidisciplinary team management.

A Rare Nasopharyngeal Teratoma Arising From the Vomer

Teratomas are rare germ cell neoplasms derived from the 3 germinal layers (ectoderm, mesoderm, and endoderm). Nasopharyngeal teratoma is a very rare teratoma arising anywhere from the oronasal cavity, regarded as an expanding, avity filling lesion, with a high mortality rate because of severe airway obstruction, especially in the neonatal period and make up only 2% of all teratomas. The authors present a case of an infant girl with a single, finger-like, hairy teratoma arising from the vomer and protruding from the mouth with bilateral complete cleft palate, cleft lip, and cleft alveolus. Complete intraoral resection of the teratoma and cleft lip repair was conducted simultaneously. Reconstruction of the cleft palate was performed at a later stage. Recurrence occurred 9 months after surgery and extended complete surgical excision was performed after recurrence, with no recurrence observed again to date. Histopathologic examination confirmed the diagnosis of congenital mature teratoma.

Congenital facial teratoma in a neonate: Surgical management and outcome

Teratomas are among the most common tumors of childhood, but craniofacial teratomas are rare. They can be diagnosed antenatally. Craniofacial teratomas may cause airway obstruction in the newborn. We present a case of a newborn male child who was diagnosed to have a facial tumor in the 8^th month of gestation. He was delivered normally and had no respiratory or feeding difficulties. He was also found to have a cleft palate. Serum alpha fetoprotein levels were normal. He underwent excision on day of life 9. At 11 months follow-up, he is well with no evidence of recurrence and good functional outcome.

Huge nasopharyngeal teratoma with a cleft palate and bifid tongue in a patient with pierre robin syndrome

PURPOSE

Nasopharyngeal teratoma is a very rare neoplasm that develops on the oronasal cavity as an expanding and cavity-filling lesion. We present a rare case of nasopharyngeal teratoma associated with a cleft palate and bifid tongue in a patient with Pierre Robin syndrome.

METHODS

A preterm male neonate of 33 weeks and 6 days was referred to our department. A protruding solid mass with approximately 7.0 × 4.0-cm size arising from the vomer and combined cleft palate and tongue covered with pinkish skin with lanugo were observed. In addition, there was a bandlike tissue connecting vomer and sublingual area, which divided and restricted the anterior portion of the tongue.

RESULTS

An early surgical intervention was decided because of problems with airways and nutrition caused by the mass. The mass was completely removed from the vomer. The histologic examination of the mass was consistent with mature teratoma. After his first operation, he was finally diagnosed with the Pierre Robin syndrome. After 4 months, a tongue reduction was conducted for macroglossia, and after 9 months, remnant teratoma excision and a palate repair were conducted using 2-flap palatoplasty.

CONCLUSIONS

A nasopharyngeal teratoma is a rare case and induces a cleft palate and bifid tongue in a preterm infant, leading to severe airway and nutritional problems. A teratoma interferes with the fusion of embryonic tissues in the early developmental period, in particular, with the palatal fusion severely prevented if the teratoma is accompanied by a Pierre Robin syndrome such as in this case.

Prenatal diagnosis of epignathus with multiple malformations in one fetus of a twin pregnancy using three-dimensional ultrasonography and magnetic resonance imaging

Epignathus is an extremely rare type of congenital teratoma arising in the oral cavity. Although it is a benign tumor, it is associated with high mortality and morbidity rates because of severe airway obstruction and other malformations. We present a case of epignathus affecting one fetus in a twin pregnancy. The tumor was associated with multiple congenital malformations including cleft palate, bifid tongue, bifid uvula, congenital heart defect, and bilateral inguinal hernias. The diagnostic value of three-dimensional ultrasonography and magnetic resonance imaging was explored with respect to antenatal counseling and peripartum management.
