Résumé

Congenital germ cell tumors are uncommon. The most common site of teratoma is in the sacrococcygeal region. Teratoma arising from the head and neck comprises less than 10% of reported cases and of these, nasopharyngeal lesions are rare. Teratomas are generally benign, and have a well recognized clinical and histopathological entity. We present a case of nasopharyngeal teratoma [NPT] associated with a wide cleft palate. A 20 day old female neonate with a teratoma of the nasopharyngeal area, and wide cleft palate was referred to our center. The protruded mass which measured 6x4x3cm, was of soft consistency, blocked the airway, and prevented oral feeding. Preoperative evaluation and imaging was performed and mass was excised 2 days after admission. Pathology revealed a well-differentiated mature solid teratoma [hairy polyp]. The patient had no complication in the post-operative period. Cleft palate was surgically repaired when 2 years old. She is now a six year old girl with normal development. Congenital nasopharyngeal teratomas are usually benign. Surgery is the treatment of choice, and should be undertaken on an urgent basis, especially in a patient who presents with signs and symptoms of airway obstruction

Résumé

The authors report the very rare case of a congenital immature teratoma arising from the nasopharyx in a full term female neonate. The tumor also extended to the oral cavity, particularly the right tonsillar fossa without intracranial involvement leading to upper airway obstruction and secondary Escherichia coli pneumonia. The immature part of the tumor in the head and neck region is not a poor prognostic indicator and chemotherapy is useless. In the presented case, the mass was widely excised without postoperative complications. To the best of our knowledge, this is the first reported case in Thailand.

Résumé

The case report of a congenital nasopharyngeal teratoma presented as an intra-amniotic sac mass was described. Histologically, the tumor was composed of highly differentiated tissue derived from three germ layers. Those tissues were partially developed as infant organs with a central core made up by bone. Haphazardly arrangement of such tissues with disorganized sketal axis helped in differentiating the mass from an asymmetric twins. The evidence of tumor attachment was seen at the retro-uvular region.
