腸閉塞をきたした子宮頸癌小腸転移の1例

We report a patient of a metastatic small intestinal tumor from uterine cervical cancer. A 76 year-old woman admitted to our hospital because of dyspnea. She showed progressive acute renal failure with pulmonary edema. Abdominal CT showed an advanced uterine cervical tumor and bilateral hydronephrosis. She was treated with temporary hemodialysis and tube nephrostomy. 1 week after admission, she presented with severe nausea, vomiting and rapidly progressive abdominal distension. We diagnosed her as strangulated ileus of the small intestine and she underwent an emergency operation. Laparotomy revealed an isolated tumor of the ileum and dilatation of the proximal small intestine without peritoneal dissemination, and a partial resection of the ileum was performed. Histopathological findings showed that the tumor was composed of squamous cell carcinoma cells, indicating that it was metastasis from uterine cervical cancer.
Metastatic small intestinal tumor from primary uterine cervical cancer is very rare. To our knowledge, only 5 cases have been reported in Japan, including the present case.
