Abstract

We report a case of bronchogenic carcinoma and subsequent oral cavity tumor. After the initial intervention for lung cancer, an oral lesion that was causing dysphagia was observed. Both punch biopsies of the bronchial and oral lesions led to diagnosis of squamous cell carcinoma. These histo­pathological results pointed to the origin of oral cavity disease being either lung cancer metastasis or a second primary oral cavity cancer and we discussed these two possibilities.
