Refractory upper gastrointestinal bleeding occurred in a patient with squamous cell carcinoma of lung—A case report and literature review

Summary Cases for lung cancer metastasizing to stomach are rare, especially for squamous cell carcinoma. A 52-year-old Chinese male had visited our hospital due to chronic coughing and hemaptysis. After examinations, chest radiography indicated the presence of right upper lobe collapse. In addition, bronchoscopic biopsy showed the presence of pulmonary squamous cell carcinoma. Before any treatments the male had admitted that he has tarry stool. The result of panendoscopy showed a submucosal tumor at greater stomach curvature with ulcerative bleeding. Biopsy from gastric tumor confirmed metastatic squamous cell carcinoma. Because of this reported case, we have decided to do further review on the clinical characteristics of reported patients who have metastatic gastric cancer from lung squamous cell carcinoma.
