Due to its rarity, cervical thymic cyst is seldom included in the differential diagnosis of a neck mass. Approximately 80 cases have been reported thus far, and most of these cases have occurred asymptomatically in children and adults. Only 5 cases have involved patients younger than 1 year of age. The authors report four new patients with thymic cyst in the neck. Two of the patients were newborns in whom the cyst caused airway obstruction and dysphagia. All four patients underwent successful resection of the lesions, with complete resolution of symptoms. The embryology, histopathology, and differential diagnosis of cervical thymic cysts are also reviewed. The authors recommend that despite its infrequent occurrence cervical thymic cyst should be considered in the evaluation of neck masses in children.
由于其罕见性，颈部胸腺囊肿很少被纳入颈部肿块的鉴别诊断中。迄今为止，大约已报道了80例病例，其中大多数病例在儿童和成人中无症状发生。仅有5例涉及1岁以下的患者。作者报告了4例新的颈部胸腺囊肿患者。其中2例为新生儿，囊肿导致气道阻塞和吞咽困难。所有4例患者均成功切除病变，症状完全缓解。本文还对颈部胸腺囊肿的胚胎学、组织病理学及鉴别诊断进行了综述。作者建议，尽管颈部胸腺囊肿发生率较低，但在评估儿童颈部肿块时仍应予以考虑。
