title: Intussusception due to vanishing colon cancer with metastasis of the regional lymph nodes: report of a case.
abstract: We present herein a case report of vanishing colon cancer with intussusception. A 70-year-old man with hematochezia was admitted to our hospital. Preoperative images showed ileus due to a colonic tumor. At operation, normograde intussusception without any tumor was recognized at the sigmoid colon. Interestingly, the regional lymph nodes were found to be invaded by tubular adenocarcinoma cells, thus suggesting that the colon cancer existed before the necrosis of the wall took place.
