Gastrointestinal metastasis of lung cancer is fairly rare, and metastasis to the duodenum is very uncommon. We report a case of duodenum and small intestine metastases of lung squamous cell carcinoma. The patient was a 66-year-old man. He was diagnosed with lung squamous cell carcinoma (T4N3M1 [mediastinum, cervical lymph node, and duodenum metastases], stage IV). He noted a sense of abdominal fullness on the evening of the day chemoradiotherapy was given, and emergency surgery was performed for suspected perforation of the digestive tract. Intraoperative findings included a tumor in the small intestine with a perforation at the tumor site; partial resection of the small intestine, including the tumor, was performed. Small intestine metastasis of lung cancer was diagnosed following histopathologic examination. When lung cancer patients complain of abdominal symptoms, it is important to consider gastrointestinal metastases in diagnosis and treatment.
肺癌的胃肠道转移相当罕见，转移至十二指肠的情况极为少见。我们报告一例肺鳞状细胞癌十二指肠及小肠转移病例。患者为一名66岁男性。他被诊断为肺鳞状细胞癌（T4N3M1[纵隔、颈部淋巴结及十二指肠转移]，IV期）。在进行放化疗当天晚上，他感到腹部胀满，因怀疑消化道穿孔而进行了急诊手术。术中发现小肠有一肿瘤，肿瘤部位有穿孔；对包括肿瘤在内的小肠进行了部分切除。经组织病理学检查确诊为肺癌小肠转移。当肺癌患者出现腹部症状时，在诊断和治疗中考虑胃肠道转移很重要。
