目的　头颈部畸胎瘤及畸胎样囊肿分析、总结。方法　对 1984年 10月至 1999年 3月有详细记载的10例畸胎瘤及畸胎样囊肿的临床特点、组织学所见、治疗方法、结果及预后进行回顾性分析、讨论。结果　头颈部畸胎瘤表现形式多样 ,多发于新生儿及儿童 ,表现为固定或活动 ,实性或囊性的包块 ,与周围组织界清。可附着于邻近的颌骨、腭部及颅底。低分化畸胎瘤表现与头颈部其它肿瘤或囊肿类似。分化程度高的畸胎瘤可见器官样结构如眼睑样皮肤赘、肢体结构等。口咽部、上颈及口底巨大畸胎瘤常导致新生儿呼吸窘迫。所有患者均采用手术切除 ,随访无复发。组织学检查见成分复杂的肿瘤组织不规则排列在一起 ,如毛囊、腺体、呼吸上皮、胃肠管、神经组织、肌肉、软骨、脂肪组织等。结论　头颈部畸胎瘤表现形式复杂多样并有其独特之处 ,宫内及产后超声波、CT、MRI检查有助于早期诊断及处理 ,早期彻底切除预后良好 Objective To analyze and summarize the teratoma teratoma and teratoid cyst. Methods The clinical features, histological findings, treatment methods, outcomes, and prognosis of 10 teratomas and teratoid cysts recorded in detail from October 1984 to March 1999 were retrospectively analyzed and discussed. Results Head and neck teratomas manifested multiple forms, mostly in newborns and children, manifested as fixed or active, solid or cystic masses, and bordered with surrounding tissue. Can be attached to the adjacent jaws, ankles and skull base. The poorly differentiated teratoma behaves like other tumors or cysts in the head and neck. Highly differentiated teratomas can have organ-like structures such as orbital skin spasms, limb structures, and the like. Oropharyngeal, upper cervical and teratogenic teratomas often cause neonatal respiratory distress. All patients underwent surgical resection without follow-up. Histological examination showed that tumor tissues with complex composition were irregularly arranged together, such as hair follicles, glands, respiratory epithelium, gastrointestinal tract, nerve tissue, muscle, cartilage, and adipose tissue. Conclusion The head and neck teratoma manifestations are complex and diverse, and have their own unique features. Intrauterine and postpartum ultrasound, CT and MRI examinations are helpful for early diagnosis and treatment. Early complete resection has a good prognosis.
