OBJECTIVE
Ectopic cervical thymus is a rare anomaly, and 50 per cent of cases occur in children. The aim of this report was to remind clinicians of this rare condition, which is part of the differential diagnosis of a paediatric neck lump.
METHOD
Case report together with literature review of the pathogenesis and management of ectopic cervical thymus.
RESULTS
The ectopic cervical thymus is a rare cause of a benign neck mass, and is thus usually misdiagnosed as lymphadenopathy or neoplasia. We discuss its embryology, aetiology, presentation, histopathology, radiology and management, with reference to the reported case.
CONCLUSION
Ectopic cervical thymus should always be considered in the differential diagnosis of a paediatric neck lump. The diagnosis can often be confirmed by cytology and radiology prior to surgical excision.
目的
异位颈胸腺是一种罕见的异常情况，50%的病例发生于儿童。本报告的目的是提醒临床医生注意这种罕见病症，它是小儿颈部肿块鉴别诊断的一部分。
方法
病例报告并结合对异位颈胸腺发病机制及治疗的文献综述。
结果
异位颈胸腺是引起良性颈部肿块的罕见原因，因此通常被误诊为淋巴结病或肿瘤。我们结合报告的病例讨论其胚胎学、病因学、临床表现、组织病理学、放射学及治疗方法。
结论
小儿颈部肿块的鉴别诊断应始终考虑异位颈胸腺。手术切除前，通常可通过细胞学和放射学检查确诊。
