A 71-year-old man diagnosed with gastric cancer was admitted for surgery. Chest X-ray on admission showed a large tumor shadow in the left upper lung field. Enhanced computed tomography scan and histological examination of the biopsied specimen showed squamous cell lung carcinoma. Upper gastrointestinal radiography showed an elevated lesion with shallow central ulceration on the anterior wall in the upper stomach, and gastrofiberscopy showed a submucosal tumor with central ulceration. Histologically, it was difficult to diagnose as metastatic gastric cancer. The man developed bleeding from the stomach tumor and underwent total gastrectomy. Histologically, the resected specimen showed metastatic gastric cancer. Clinically, apparent metastasis from primary lung cancer to the stomach is rare. We reviewed 80 cases of metastasis from primary lung cancer to the stomach in the Japanese literature.
