Abstract
A 76 year-old male was admitted because of slight fever and left chest pain. Chest-X-ray examination showed atelectasis of the left upper and right middle lobes. Bronchograms showed that the left upper division bronchus and right middle lobe bronchus were obstructed by irregular bronchial tumors and the right upper bronchus also showed a filling deficit of contrast material. Bronchoscopy findings showed that three polyp-like prominences with irregular surfaces were present at the orifice of the left upper division, right upper and right middle lobe bronchus respectively and these polypoid tumors were independent of each other. However there were no remarkable changes in both main bronchi and other bronchi. Histologically the three tumors were squamous cell carcinoma. Therefore we considered this case as primary triple cancer of the lung. We treated this case with intratumoral injection of OK-432 and the tumors were observed to decrease in size.
