A Case of Colonic Metastasis from Borderline Ovarian Cancer

This report describes the case of a patient who had previously undergone surgery for resection of bilateral ovarian tumors and after 5 years presented with colonic metastasis. A 70-year-old woman visited the hospital for a clinical survey due to severe anemia. In 2007, the patient was diagnosed with cancer (papillary serous adenocarcinoma) in both ovaries. The patient had undergone total abdominal hysterectomy with bilateral salpingo-oophorectomy followed by post-operative adjuvant chemotherapy. After treatment, the patient was stable during follow-up. After 5 years, she underwent incidental colonoscopic examination because of severe anemia. The colonoscopic findings revealed an elevated irregular lesion in the descending colon. Colonic metastasis from the papillary serous adenocarcinoma of the ovary was confirmed by immunohistochemical staining during the pathological diagnosis.
