Oral teratomas are rare entities.
A patient was referred for elevations in the maternal serum alpha-fetoprotein. On ultrasound examination, a cyst was seen protruding from the fetal mouth. Postnatally, a teratoma was found to be filling the neonate's oral cavity.
This case illustrates problems in determining the etiology of head and neck masses antenatally. It also shows that teratomas can appear to regress and yield positive amniotic fluid alpha-fetoprotein and acetyl-cholinesterase. The appropriate perinatal management of this potentially devastating disorder includes preparation for establishing an airway following delivery.
口腔畸胎瘤是罕见的疾病。
一名患者因母体血清甲胎蛋白升高而前来就诊。超声检查发现一个囊肿从胎儿口腔突出。出生后，发现一个畸胎瘤占据了新生儿的口腔。
该病例说明了产前确定头颈部肿块病因存在的问题。它还表明畸胎瘤可能看似消退，并导致羊水甲胎蛋白和乙酰胆碱酯酶呈阳性。对这种潜在的严重疾病进行适当的围产期管理包括为分娩后建立气道做好准备。
