An epiglottic mass (EM) is rarely found in neonates and poses life-threatening airway complications. We present the case of an infant urgently transferred from Belize via the World Pediatric Project with a lingual EM. The EM was misdiagnosed twice. The patient's home country of Belize initially misdiagnosed the EM as an elongated uvula and then again as an esophageal polyp. The true nature of the upper airway mass (UAM) was only discovered intraoperatively on rigid bronchoscopy as a lingual, mobile EM. Pathology of the lingual EM showed fibrovascular tissue with an area of exuberant capillary proliferation, cartilage, and ectopic thymic tissue. A second, smaller mass was also discovered in the left piriform sinus. The pathology revealed the presence of fibrovascular tissue, mucus glands, and a small amount of skeletal muscle. To the best of our knowledge, a thorough review of the literature reveals that this is the first description of ectopic thymic tissue presenting as an EM.
会厌肿物（EM）在新生儿中很少见，且会引发危及生命的气道并发症。我们报告一例经世界儿科项目从伯利兹紧急转运来的患有舌部EM的婴儿病例。该EM被误诊了两次。患者的祖国伯利兹最初将EM误诊为悬雍垂过长，之后又误诊为食管息肉。上气道肿物（UAM）的真实性质仅在术中硬支气管镜检查时才被发现是舌部可移动的EM。舌部EM的病理显示为纤维血管组织，伴有毛细血管增生旺盛区域、软骨和异位胸腺组织。在左侧梨状窝还发现了第二个较小的肿物。病理显示存在纤维血管组织、黏液腺和少量骨骼肌。据我们所知，对文献进行全面回顾后发现，这是首例将异位胸腺组织表现为EM的描述。
