SummaryOvarian metastases are found in 3‐4 per cent of female patients with carcinomas of the colon or rectum. They may be very large, like primary ovarian tumors. Ten women with ovarian metastases from colonic or rectal carcinoma were seen at Ochsner Foundation Hospital over an 11‐year period. In four of these women ovarian metastases were found on physical examination, while in the other six they were found incidentally at surgery or necropsy. None of these tumors histologically resembled the classic Krukenberg tumor; all were hsitologically identifiable as metastases from carcinomas of the large intestine. Surgical resection was done in nine women. All are either dead of, or alive with, residual malignancy.Prophylactic oophorectomy should be considered for all postmenopausal women, and for premenopausal women with obvious ovarian tumors, extensive serosal involvement by the colonic or rectal lesion, or extensive metastases to regional lymph nodes.
