Abstract
A 58-year-old woman underwent surgery for transverse colon cancer at the previous hospital on March 2008. When she got outpatient treatment on August 2010, a follow-up computed tomography (CT) showed the mass in rectouterine pouch and the left ovarian tumor. However her doctor recommended chemotherapy, she visited our hospital for the second opinion. Fluorodeoxyglucose positron emission tomography (FDG-PET) examination revealed the localized rectouterine pouch recurrence and the left ovarian metastasis. She underwent low anterior resection of rectum, hysterectomy and bilateral adnexectomy. The mass in rectouterine pouch penetrated into the vaginal fornix and formed ulcer three centimeters in diameter. The histopathological examination revealed mucinous adenocarcinoma in both the mass in rectouterine pouch and the left ovarian tumor. 30 months after the adjuvant chemotherapy (XELOX, 8 coureses), she has experienced recurrence-free survival at this point. Because, in many cases, the peritoneal dissemination of colon cancer is multiple, the indication for surgical treatment is rare. But, if curative resection is done for the localized peritoneal dissemination like our case, long survival can be expected.
