Huge teratoma of the nasopharynx.

Congenital immature teratoma of the nasopharynx is a very rare form of extragonadal teratoma. In this article, management of a newborn with nasopharyngeal teratoma who underwent tumor resection is reported. The tumor, which originated from the nasopharynx, almost filled the oral cavity and protruded through the mouth, with its external part comparable to the size of the head. She could breath when the head and mass were turned to the left. For safe management of these cases, prenatal evaluation, careful preoperative assessment of the airway, sufficient preparation, and intubation by an expert are mandatory. Perioperative bleeding and obstruction of airway by the tumor or its remnant could render the case difficult.
