A 62-year old man with an abnormal chest radiograph was referred to our hospital for further evaluation. Chest computed tomography (CT) revealed a 3.0 cm tumor on the hilum of the right S3 segment. Bronchofiberscopic findings showed a polypoid tumor arising from right B3. Brushing cytology under bronchofiberscopy couldnot diagnose the tumor. The tentative preoperative diagnosis was primary lung cancer or a metastatic lung tumor. To confirm the histopathological diagnosis, a right upper lobectomy was performed. Intraoperative histopathological examination showed a pulmonary inflammatory pseudotumor.
