[A case of solitary endobronchial metastasis of hepatocellular carcinoma].

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.
