Abstract

Upper gastrointestinal bleeding as a result of gastrointestinal metastases from lung cancer is extremely rare. We report two cases of patients with duodenal metastases from lung adenocarcinoma presented with recurrent melena. Histopathological examination and immunohistochemical staining of the duodenal biopsies supported the diagnosis of metastatic lung adenocarcinoma.
