Cervical teratomas are rarely encountered in adults. We report herein the case of a 21-year-old woman who was admitted to our hospital for surgical treatment of a neck tumor, 7.5 x 4.5 x 2.7 cm in size, located in the left lower pole of the thyroid. Ultrasonography (US) and computed tomography (CT) revealed a multicystic tumor. The levels of carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), and squamous cell carcinoma-related antigen (SCC) in the cystic fluid were extremely elevated in contrast to the normal levels found in the serum. The tumor was completely excised and histological examination revealed it to be composed of elements derived from the three germ layers, confirming a diagnosis of benign cystic teratoma.
成人颈部畸胎瘤极为罕见。我们在此报告一例21岁女性患者，因颈部肿瘤入院接受手术治疗。该肿瘤大小为7.5×4.5×2.7厘米，位于甲状腺左下极。超声检查（US）和计算机断层扫描（CT）显示为多囊性肿瘤。囊液中癌胚抗原（CEA）、糖类抗原19-9（CA19-9）和鳞状细胞癌相关抗原（SCC）水平极度升高，与血清中的正常水平形成对比。肿瘤被完整切除，组织学检查显示其由来自三个胚层的成分组成，确诊为良性囊性畸胎瘤。
