A Rare Case of Hurthle Cell Carcinoma with Endobronchial Metastasis

Endobronchial metastases (EBM) are frequently seen in breast, renal and colon carcinomas. However, to our knowledge, only one case has ever been reported as EBM secondary to Hurthle cell carcinoma (HCC) in the literature. A 57-year-old woman had a bilateral total thyroidectomy for thyroid mass in 1990 that was diagnosed as HCC. She was admitted to our outpatient clinic in August 1999, with symptoms of cough, sputum, and right-sided pleuritic pain for the last seven months. In the bronchoscopic examination, two endobronchial lesions were seen. Pathological evaluation of the bronchoscopic samples was diagnosed as“Hurthle cell carcinoma”of thyroid. We suggest that, although rare, HCC should be considered in the differential diagnosis of the endobronchial metastasis.
