Lung cancer is the leading cause of cancer mortality in the developed world, and often presents with metastatic disease. Metastatic lung cancer rarely presents with gastrointestinal symptoms, but we report a case of an elderly male with metastatic lung carcinoma to the cecum who presented with melena. The patient required blood transfusions, but eventually died of septic shock. This case is consistent with previously reported cases of lung cancer metastatic to the gastrointestinal tract which suggest that tumor-associated bleeding in this patient population is a pre-terminal event.
肺癌是发达国家癌症死亡的主要原因，且常伴有转移性疾病。转移性肺癌很少出现胃肠道症状，但我们报告了一例老年男性患者，其盲肠出现转移性肺癌并伴有黑便。该患者需要输血，但最终死于感染性休克。此病例与先前报道的肺癌转移至胃肠道的病例一致，这表明该患者群体中与肿瘤相关的出血是临终前的事件。
