Teratomas are the most common congenital tumors, but neoplasms of the nasopharynx are rare in neonates and children. Four histologic types of nasopharyngeal teratomas occur-dermoids, teratoids, true teratomas, and epignathi-of which dermoids comprise the vast majority. A case is presented of a neonate born at term exhibiting signs of respiratory difficulty, which were found to be caused by a true teratoma of the nasopharynx. A review of several large case series of pediatric teratomas confirmed the rarity of occurrence at this site. An extensive review of case reports identified those meeting the criteria of true teratomas of the nasopharynx; the characteristics of these cases are delineated.

Malignant tumors of the head and neck are rare in children, but it is important to know these lesions and identify them early in order to have a good outcome for these patients. Benign lesions of the head and neck are much more frequent and have an excellent prognosis. For this reason, it is necessary to recognize the warning signs and symptoms and understand when to refer the patient to a reference center for the treatment of these pathologies.

Introduction And Importance: Congenital teratomas arising from the oropharynx, also known as epignathus, are exceedingly rare tumours occurring in 1:35,000-200,000 live births. Although histologically benign, these tumours are often difficult to diagnose antenatally and can cause life-threatening airway obstruction in the newborn.
Case Presentation: We present a case of a full-term female infant presenting at birth with respiratory distress and stridor.
