Background. A case of lung cancer probably induced by a intrabronchial foreign body is very rare. Patient. A 69-year-old man was admitted with wheeze and dyspnea. He had smoked about 20 cigarettes a day for fifty years. He aspirated a fish bone in about 1992. Though he consulted a otolalyngologist, the fish bone had been left since then. He started to have a wet cough from 1999 and was treated as chronic bronchitis by a near physician. But his symptom got worse from January in 2002. He had a mass shadow in right hilum with in the right upper lung field in chest radiograph. We performed bronchoscopy which showed upheaving leasion almost stenosing the right main bronchus right under carina and a foreign body like a gray stick falling into it. Histological findings of the upheaving lesion showed squamous cell carcinoma, and squamous metaplasia around it. The foreign body is considered to be a fish bone by his story. We diagnosed primary lung cancer (squamous cell carcinoma T3N2M0 stage IIIA). He was treated by chemotherapy and radiation therapy, and the tumor was almost disappeared with almost normal chest radiograph and CT. Conclusion. We considered that lung cancer was probably induced by a intrabronchial foreign body along with heavy smoking.
