Metastases to breast from extramammary primaries are very rare events. These lesions differ from primary breast carcinomas and they are known to have poor prognosis. Discrimination between metastatic tumors and primary breast carcinomas are usually done by clinical and pathological evaluation including immunohistochemistry. Here we report an unusual case of ovarian epithelial carcinoma which was initially diagnosed as to give metastasis to breast 17 months later than the first diagnosis of ovarian carcinoma. Clonality evaluation revealed that breast and ovarian tumors were metachronous dual primaries. [Turk J Cancer 2007;37(1):27-30]
