Lung cancer associated with a single simultaneous solitary metastatic lesion in stomach: a case report with the review of literature.

Abstract

Metastatic tumors of the stomach are rare. Although neoplasms from almost every tissue have been reported to metastasize to the stomach, lung cancer is a rare cause. We report the case of 46-years-old man presented with superior Vena Cava syndrome. Histopathological diagnosis was non-small cell lung cancer with computed tomography-guided needle biopsy of lung. Since gastric symptoms occurred during follow up of patient, upper gastrointestinal endoscopy performed. Upper gastrointestinal endoscopy and biopsy showed metastasis of stomach secondary to primary squamous cell lung cancer and additionally lack of another distant site metastasis indicated that gastric region was the single site of tumor spread.
