Duodenal metastases secondary to lung cancer are very rare and most of the time asymptomatic. When symptomatic they usually present with bowel obstruction or perforation. We here describe the case of a 68 year-old man with a solitary metastasis in the duodenum from a non-small cell lung carcinoma (NSCLC). The patient presented with reduced exercise tolerance and iron deficiency anemia without clinical gastrointestinal blood loss. Further investigation showed a tumor in the left upper lung lobe and a duodenal metastasis for which he received chemotherapy. To the best of our knowledge this is the first case report of iron deficiency anemia as initial presentation of a duodenal metastasis from a NSCLC.
肺癌继发十二指肠转移非常罕见，大多数情况下无症状。出现症状时，通常表现为肠梗阻或穿孔。我们在此描述一例68岁男性，患有非小细胞肺癌（NSCLC）十二指肠孤立转移。患者表现为运动耐量下降和缺铁性贫血，无临床胃肠道失血。进一步检查发现左上肺叶有肿瘤及十二指肠转移，为此他接受了化疗。据我们所知，这是首例以缺铁性贫血为NSCLC十二指肠转移初始表现的病例报告。
