Abstract
We reported a case of small lung cell carcinoma with gastric metastasis. A 62-year-old man was admitted to our hospital for further examination of a gastric suhmucasal tumor. The chest X ray film on admission showed a tumor-1ike shadow in the right lower lung field. CT-guided needle aspiration biopsy (CT-NAB) of the lung tumor proved small cell carcinoma. The upper gastrointestinal endoscopic examination showed a protruding lesion with central ulceration on the anterior wall of the lower body of the stomach. Gastroscopic biopsy of the submucosal turnor-1ike lesion demonstrated small cell car-cinama identical to the histological findings of CT-NAS specimens of the lung tumor. The patient was effectively treated with chemotherapy. The gastric metastasis from primary lung cancer rarely occurs and thecase in which the improvement of the gastric rnetastasis is confirrrled endoscopically, is very rare.
