Teratoma is the most common germ cell tumour in childhood. Teratoma typically arises in the sacrococcygeal region, gonads and mediastinum. The head and neck region is seldom involved. Teratomas of the neck region represent one of the most unusual causes of respiratory distress during the neonatal period. We present a case of an immature teratoma in the parapharyngeal space presenting with airway obstruction in an infant. Surgeons should consider the possibility of immature teratoma in the head and neck region in the differential diagnosis of respiratory distress in an infant, even if the patient does not have an external deformity.
畸胎瘤是儿童期最常见的生殖细胞肿瘤。畸胎瘤通常发生于骶尾部、性腺和纵隔。头颈部很少受累。颈部畸胎瘤是新生儿期呼吸窘迫最不常见的原因之一。我们报告一例婴儿咽旁间隙未成熟畸胎瘤伴气道梗阻的病例。即使患者没有外部畸形，外科医生在婴儿呼吸窘迫的鉴别诊断中也应考虑头颈部未成熟畸胎瘤的可能性。
