We report the case of a 73-year-old man who developed metastatic small-cell lung cancer to the bony external auditory canal (EAC). The patient had only recently been diagnosed with his primary carcinoma. The metastasis presented as a bulky, fleshy, bleeding mass in the right EAC. Biopsy of the metastasis revealed that its histologic characteristics were identical to those of the primary. This case is of interest because this was a unique type of metastasis to the EAC. Although there are reports in the literature of lung cancer and even small-cell cancer metastasizing to the temporal bone, we could find no previously published report of a small-cell lung carcinoma metastasizing to the EAC.
我们报告了一例73岁男性患者，其发生了转移性小细胞肺癌至外耳道骨部（EAC）。该患者最近才被诊断出原发性癌。转移灶表现为右侧EAC内一个巨大、肉质、出血性肿块。转移灶活检显示其组织学特征与原发性肿瘤相同。该病例值得关注，因为这是一种转移至EAC的独特类型。尽管文献中有肺癌甚至小细胞癌转移至颞骨的报道，但我们未找到先前发表的小细胞肺癌转移至EAC的报告。
