[Small bowel metastasis from large cell carcinoma of the lung: report of a case].

The case of a 44-year-old man with metastatic tumor of the small intestine from large cell carcinoma of the lung was reported. The patient underwent exploratory thoracotomy because of tumor invasion into the left ventricle. He was discharged from our department after chemotherapy and irradiation. However, he was again admitted because of the development of anemia secondary to melena. An abdominal ultrasonography revealed ascites and tumor of the small intestine. Symptoms of ileus also developed. A laparotomy was performed. The metastatic tumors were found in the jejunum, and resection of jejunum was performed. The postoperative course of the patient was uneventful, and he survived one month after laparotomy. Small bowel metastasis of lung cancer, which is unusual pattern of metastasis, is also reviewed.
