A 74-year-old man was admitted to Keio University Hospital because of an abnormal shadow in the right upper lung field on chest roentgenogram. Bronchoscopic examination revealed malignant cells, by which large cell carcinoma of the lung was diagnosed. Systemic survey for metastasis disclosed an ulcerated tumor on the greater curvature of the stomach. Endoscopic examination showed an elevated submucosal tumor suggesting submucosal metastasis of lung cancer to the stomach. A review of 473 autopsies of primary lung cancer at Keio University from 1958 to 1987 showed 16 cases with gastric metastasis (3.4%). Two of 16 cases were detected clinically. Gastric metastases were proven in 15.6% of autopsy cases of large cell carcinoma of the lung. Forty-three cases of primary lung cancer with gastric metastasis were reported in the Japanese literature from 1965 to 1990. Thirteen of these cases had large cell carcinoma.
