Metastasis to the ovary is relatively rare after colorectal cancer surgery. We report 2 cases of ovarian metastasis requiring oophorectomy after curative colonic cancer resection. Case 1, a 27-year-old premenopausal woman, underwent resection for descending colon cancer based on a histological diagnosis of n1, curative A. Six months after surgery, bilateral ovarian tumors were found, necessitating bilateral oophorectomy and hysterectomy under a histological diagnosis of bilateral ovarian metastasis from colon cancer. She died of carcinomatous peritonitis and hepatic metastasis 18 months after colon cancer surgery. Case 2, 39-year-old premenopausal woman, underwent resection of descending colonic cancer, diagnosed as n1, curative A, histologically. Eleven months after surgery, a ovarian tumor was found and she underwent bilateral oophorectomy, under a histological diagnosis of right ovarian metastasis from colonic cancer. She remains well 19 months after colon cancer surgery. Both cases were premenopausal, diagnosed as lower advanced colon cancer with lymph node metastasis. We must follow up such patients and be on the outlook for ovarian metastasis from colorectal cancer. We review cases of ovarian metastasis necessitating oophorectomy after curative colon cancer resection in the Japanese literature.
