          A case report of a postmenopausal woman, who presented with a pelvic mass, abdominal distension and shock. She was found to have a colon cancer, large right ovarian tumor with necrosis and ruptured, causing intraperitoneal hemorrhage and peritonitis. Pathological diagnosis was carcinoma of sigmoid colon and metastasis to right ovary, which was confirmed by immunohistochemical study. A review of the literature suggests that ovarian metastasis from primary colon carcinoma is not rare. Frequently, the ovarian tumor causes symptoms sooner than the primary carcinoma. Generally, macroscopic metastatic disease to the ovary is a poor prognostic factor in colon cancer and consideration should be given to the performance of prophylactic oophorectomy during colon resection for carcinoma. The following case illustrates the difficulties encountered in differentiating a primary ovarian neoplasm from a metastatic tumor in the ovary.
