Blood-borne metastatic involvement of the gastric mucosa as a result of cancer is a rare occurrence. The tumors which were most commonly reported to metastasize to the stomach include melanoma, breast carcinoma, and lung carcinoma. Some reports document that large cell carcinoma and squamous cell carcinoma of the lungs have a higher pre- dilection for gastrointestinal tract metastases. Upper gastrointestinal endoscopic findings of metastatic lesions may vary but often produce a characteristic single or multiple bulls eye or target lesion. Therefore, whenever single or multiple target lesions are seen in the stomach on upper gastrointestinal endoscopy or barium study, the examination should include careful radiographic evaluation of the chest. Moreover, when the patient is known to have lung cancer, metastatic disease should be suspected. With a correct diagnosis and proper treatment, relief of symptoms and prolongation of life can sometimes be achieved, A case in reported involving squamous cell lung cancer with stomach metastasis in a 73 year-old woman. The patient was diagnosed by bronchoscopy, upper gastrointestinal endoscopy, chest CT, and abdominal CT. The chest and abdominal CT revealed a poorly marginated, lobulated, and 4 x 3 cm sized mass lesion in the right lower lobe causing obstruction of right lower lobe bronchus with invasion to the left atrium. right inferior pulmonary vein, and superior vena cava. Mediastimal lymph node enlargement and liver metastasis was also detected. Upper gastrointestinal endoscopy showed two "bulls eye" lesions with different sizes and two nodules without tip ulceration.
