A Case of Complete Intussusception Induced by Cancer of the Appendix

A case of complete Intussusception induced by cancer of the appendix is reported. The patient was a 74-year-old woman. Barium enema and colonofiberscopy were performed because of a positive occult blood on a fecal examination. A diagnosis of colon cancer was made preoperatively, and laparoscopic-assisted ileocolec-tomy with dissection of regional lymph nodes was performed. Intussusception of the appendix was found intraoperatively and in the postoperative specimen. Microscopic examination revealed well differentiated ade-nocarcinoma limited to the proper muscle of the appendix. Since cancer of the appendix is rare, and diagnosis of Intussusception with cancer of the appendix is very difficult, this disease should always be taken into con-sideration when diagnosing diseases of the cecum.
