title: [A case of intussusception due to intestinal metastasis of renal carcinoma].
abstract: Adult intussusceptions due to metastatic intestinal-tumor are very rare. A 71-year-old man with an intussusception due to intestinal metastasis of renal carcinoma is reported. To our knowledge, this is the third such patient in the Japanese literature. The patient was suffered from an intestinal obstruction six months after his renal carcinoma was detected. Laparotomy was performed, revealing that he had developed a jejunojejunal intussusception due to metastasis of renal carcinoma. The early diagnosis of metastatic intestinal tumor is difficult. It is important to bear in mind that patients with malignant tumor may already have metastasis.
