OBJECTIVES
The aim of the study was to present a case of small cell carcinoma arising from the tonsil with metastasis to the external auditory canal (EAC) and associated facial nerve paralysis.
METHODS
This study includes a case report and review of the literature.
CONCLUSIONS
Extrapulmonary small cell carcinoma from the head and neck is rarely described and carries a poor prognosis. It often presents with widely metastatic disease. To our knowledge, this is the first case report describing extrapulmonary small cell carcinoma from the tonsil with metastatic disease to the EAC. Irregular lesions in the EAC must be considered suspicious for metastasis in a patient with a history of cancer.
目的
本研究旨在报告一例发生于扁桃体的小细胞癌，其转移至外耳道（EAC）并伴有面神经瘫痪。
方法
本研究包括一例病例报告和文献复习。
结论
头颈部的肺外小细胞癌少见，预后差，常伴有广泛转移。据我们所知，这是首例描述扁桃体肺外小细胞癌伴 EAC 转移的病例。对于有癌症病史的患者，EAC 不规则病变必须被视为转移的可疑征象。
