Upper Gastrointestinal Bleeding Due to Metastatic Lung Adenocarcinoma in the Stomach and Duodenum

Study design: Case Report
Abstract: There are very few reports of bloodborne metastasis of lung adenocarcinoma to the gastrointestinal tract, primarily due to poor prognosis and short survival rate of metastasized carcinoma. We present a case of a 79-year-old man with a medical history of lung adenocarcinoma, who presented with complaints of weakness and melena for 1 week. He had symptomatic anemia, for which he was transfused with blood. Esophagogastroduodenoscopy showed a 10 mm sessile polyp in the gastric body that was removed. One month later, the patient presented with a similar complaint, and another esophagogastroduodenoscopy revealed 2 ulcerated lesions in the second portion of the duodenum. These lesions were treated by hemostatic clip placement and heater probe coagulation. Biopsy of lesions demonstrated thyroid transcription factor 1 and Napsin-positive tumor cells, consistent with lung adenocarcinoma. Owing to the poor prognosis of lung adenocarcinoma metastasizing to the lymph nodes, stomach, and duodenum, the patient was transferred to hospice care.
