Metastatic duodenal tumor is rare. We report 2 cases of the metastatic duodenal tumor whose primary site was the lung. Case 1; A 49-year-old man was admitted to our hospital for further examination of neck tumor. Histological findings of the tumor showed undifferentiated adenocarcinoma. Chest X-ray films showed infiltrate shadow in right upper lung field. Cytology obtained by endoscopic brushing of the lung tumor revealed adenocarcinoma. He developed hematernesis. Upper gastrointestinal endoscopic examination repealed multiple polypoid lesions with central depression in the 2nd portion of the duodenum. Biopsy from these lesions showed poorly differentiated adenocarcinoma. Case 2;A 72-year-old man was admitted for further examination of chest abnormal shadow.Chest X-ray films showed left hilar tumor (4× 5cm). Endobronchial biopsy of the lung showed squamous cell carcinoma. Because of occult bleeding in the feces, gastrointestinal endoscopic examination was done and multiple polypoid lesions with central depressionwere found in the bulbs and the 2nd portioh of the duodenum. H istologically, these tumorsproved to be squamous cell carcinoma.
