An 80-year-old man was admitted in October, 2002 with blood-tinged sputum. He had already been treated for hepatocellular carcinoma (HCC). The chest radiograph and chest CT scan showed a solitary pulmonary mass in the left lower lobe. The serum alpha fetoprotein (AFP) was elevated to 261 ng/ml. Fiberoptic bronchoscopy revealed an endobronchial tumor at left B8a and the results of brushing cytology were compatible with HCC. We confirmed the diagnosis by immunohistochemical staining using anti-AFP antibody. Endobronchial metastatis of HCC is rare and immunohistochemical staining was useful for diagnosis.
一名80岁男性于2002年10月因痰中带血入院。他此前已接受过肝细胞癌（HCC）治疗。胸部X线片和胸部CT扫描显示左肺下叶有一个孤立性肺肿块。血清甲胎蛋白（AFP）升高至261 ng/ml。纤维支气管镜检查发现左B8a处有支气管内肿瘤，刷检细胞学结果与HCC相符。我们通过使用抗AFP抗体的免疫组织化学染色确诊。HCC的支气管内转移罕见，免疫组织化学染色有助于诊断。
