Renal cell carcinoma (RCC) is known to form micrometastases in unusual organs. This report describes a case of a RCC metastasis to the breast that was identified 20 years after nephrectomy. The patient, a 68-year-old female, presented after a new abnormality was found on a screening mammogram. The biopsy, which was reviewed by several pathologists, revealed a renal cell carcinoma metastasis. Imaging confirmed no other metastases, and she was treated with a partial mastectomy. This case highlights how RCC metastases can be found many years after a nephrectomy, and staining for RCC should be considered in patients with this history and a newly identified breast mass.<\/jats:p>","DOI":"10.1177\/00031348231161711","type":"journal-article","created":{"date-parts":[[2023,3,6]],"date-time":"2023-03-06T09:59:16Z","timestamp":1678096756000},"page":"3541-3542","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Case Report of Renal Cell Carcinoma Metastasis to the Breast"],"prefix":"10.1177","volume":"89","author":[{"given":"Rebecca O.","family":"Breese","sequence":"first","affiliation":[{"name":"Department of Surgery, Eastern Virginia Medical School, Norfolk, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kara","family":"Friend","sequence":"additional","affiliation":[{"name":"Department of Surgery, Eastern Virginia Medical School, Norfolk, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,3,6]]},"reference":[{"key":"bibr1-00031348231161711","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(197206)29:6<1691::AID-CNCR2820290637>3.0.CO;2-4"},{"key":"bibr2-00031348231161711","doi-asserted-by":"publisher","DOI":"10.1016\/j.breast.2005.09.009"},{"key":"bibr3-00031348231161711","doi-asserted-by":"publisher","DOI":"10.3389\/fonc.2020.00709"},{"key":"bibr4-00031348231161711","doi-asserted-by":"publisher","DOI":"10.1023\/A:1017990625298"}],"container-title":["The American Surgeon\u2122"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/00031348231161711","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/00031348231161711","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/00031348231161711","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T12:37:11Z","timestamp":1777379831000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.1177\/00031348231161711"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,3,6]]},"references-count":4,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2023,8]]}},"alternative-id":["10.1177\/00031348231161711"],"URL":"https:\/\/doi.org\/10.1177\/00031348231161711","relation":{},"ISSN":["0003-1348","1555-9823"],"issn-type":[{"value":"0003-1348","type":"print"},{"value":"1555-9823","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,3,6]]}}}
