A 69\u2010year\u2010old woman presented with abnormal uterine cervical cytology (atypical glandular cells without tumor diathesis) 30\u2009years after undergoing breast cancer surgery. Magnetic resonance imaging revealed a 38\u2010mm cervical mass. Modified radical hysterectomy was performed. The resected specimen exhibited an immunohistochemical profile of GATA3(+)\/mammaglobin(+)\/PAX8(\u2212), which definitively excluded primary cervical adenocarcinoma and confirmed the diagnosis of metastatic invasive ductal carcinoma. Crucially, although the primary tumor was hormone receptor\u2010positive, cervical metastasis exhibited receptor conversion to HER2\u2010positive status. This case underscores the importance of considering metastatic breast cancer in the differential diagnosis of cervical masses in breast cancer survivors regardless of the disease\u2010free interval. This further highlights the necessity for receptor re\u2010evaluation in metastatic lesions to guide appropriate targeted therapy.<\/jats:p>","DOI":"10.1111\/jog.70509","type":"journal-article","created":{"date-parts":[[2026,9,29]],"date-time":"2026-09-29T04:51:44Z","timestamp":1790657504000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Metastasis of Invasive Ductal Carcinoma of the Breast to the Uterine Cervix 30\u2009Years Post\u2010Mastectomy: A Case Report"],"prefix":"10.1111","volume":"52","author":[{"given":"Taro","family":"Miyake","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology National Defense Medical College Hospital  Saitama Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hidenori","family":"Sasa","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology National Defense Medical College Hospital  Saitama Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3524-6452","authenticated-orcid":false,"given":"Tsubasa","family":"Ito","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology National Defense Medical College Hospital  Saitama Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takanori","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine National Defense Medical College Hospital  Saitama Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takako","family":"Sato","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine National Defense Medical College Hospital  Saitama Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sho","family":"Ogata","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine National Defense Medical College Hospital  Saitama Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masashi","family":"Takano","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology National Defense Medical College Hospital  Saitama Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,28]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.7759\/cureus.62523"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365\u20102303.2004.00211.x"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.crwh.2024.e00607"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ygyno.2004.07.006"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/jnci\/djab202"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1701830"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1186\/bcr767"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/1097\u20100142(19840501)53:9<1978::aid\u2010cncr2820530929>3.0.co;2\u20101"},{"key":"e_1_2_11_10_1","first-page":"637","article-title":"Metastatic Patterns of Invasive Lobular Versus Invasive Ductal Carcinoma of the Breast","volume":"114","author":"Borst M.
