At 16 months after the diagnosis of rectal mucinous adenocarcinoma, a breast mass was confirmed by ultrasonography and identified by pathology and immunohistochemistry as a metastasis from the rectal cancer. Treatments included chemotherapy (6 cycles: 300 mg irinotecan on day 1, 4.5 mg raltitrexed on day 2, 450 mg bevacizumab on day 3), radiotherapy, and surgical resection. Two years of follow-up examinations (6-months intervals) showed no evidence of recurrence or novel distant metastasis.<br><strong>Conclusion<\/strong><br>Breast metastasis from rectal carcinoma is a rare secondary malignancy. Final diagnosis can be established by histopathology and immunohistochemistry.<br><strong>Key words:<\/strong> Breast cancer; Rectal carcinoma; Metastasis; Case report; Secondary malignancy; Review<\/p>\n\n\n\n<div class=\"wp-block-buttons\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link\" href=\"https:\/\/www.mmj.mw\/wp-content\/uploads\/2021\/09\/Wei-Xian.pdf\">Download PDF<\/a><\/div>\n<\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dan-Dan Wang1, Su-Jin Yang1, Wei-Xian Chen*2 Department of Breast Surgery, The First Affiliated Hospital of Nanjing Medical University, Nanjing 210029, Jiangsu Province, China Department of Breast Surgery, The Affiliated Changzhou No. 2 People\u2019s Hospital of Nanjing Medical University, Changzhou 213000, JiangsuProvince, China Correspondence: Wei-Xian Chen (chenweixian@njmu.edu.cn) AbstractBackgroundMetastasis from extramammary primary tumor to breast is extremely [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[113],"tags":[67],"_links":{"self":[{"href":"https:\/\/www.mmj.mw\/index.php?rest_route=\/wp\/v2\/posts\/12129"}],"collection":[{"href":"https:\/\/www.mmj.mw\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.mmj.mw\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.mmj.mw\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.mmj.mw\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=12129"}],"version-history":[{"count":1,"href":"https:\/\/www.mmj.mw\/index.php?rest_route=\/wp\/v2\/posts\/12129\/revisions"}],"predecessor-version":[{"id":12131,"href":"https:\/\/www.mmj.mw\/index.php?rest_route=\/wp\/v2\/posts\/12129\/revisions\/12131"}],"wp:attachment":[{"href":"https:\/\/www.mmj.mw\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=12129"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.mmj.mw\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=12129"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.mmj.mw\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=12129"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
