A rare case of gastric metastasis originating from primary lung adenocarcinoma: a case report

Unlike liver and lung, the stomach is rarely a metastatic location for cancers. We report a case of a 62-year-old man known to have lung adenocarcinoma poorly differentiated presented with melena 1 month after diagnosis. Upper endoscopy revealed an ulcerated tumor in the prepyloric antrum. The diagn...

Sumario:Unlike liver and lung, the stomach is rarely a metastatic location for cancers. We report a case of a 62-year-old man known to have lung adenocarcinoma poorly differentiated presented with melena 1 month after diagnosis. Upper endoscopy revealed an ulcerated tumor in the prepyloric antrum. The diagnosis of gastric metastasis from pulmonary cancer was confirmed by the immunohistochemical staining for the thyroid transcriptional factor-1 and the pattern cytokeratine CK7+/CK20-. In conclusion, gastric metastasis from primary lung cancer is a rare phenomenon that every clinician must keep in mind.
