We present a case of a 62\u2010year\u2010old woman with a 2\u2010year history of persistent dysuria, urinary frequency, and urgency. On physical examination, a firm, non\u2010tender suprapubic mass was detected. Cystoscopy was performed and a bladder mass was detected. After obtaining the biopsy, pathology confirmed a mucinous signet\u2010ring cell type adenocarcinoma of urachal origin with negative margins and no vascular or perineural invasion. Following negative tumor markers, colonoscopy and CT scans for metastasis, the patient underwent partial cystectomy with tumor resection. No adjuvant therapy was administered. At 6\u2010month follow\u2010up, the patient was asymptomatic, and imaging showed no disease progression.<\/jats:p>","DOI":"10.1002\/ccr3.71420","type":"journal-article","created":{"date-parts":[[2025,11,7]],"date-time":"2025-11-07T04:51:46Z","timestamp":1762491106000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Signet\u2010Ring Cell Type Adenocarcinoma of the Urachus: A Rare Case"],"prefix":"10.1002","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-2329-3718","authenticated-orcid":false,"given":"Samin","family":"Khannejad","sequence":"first","affiliation":[{"name":"School of Medicine Shahid Beheshti University of Medical Sciences  Tehran Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sevim","family":"Soleimani","sequence":"additional","affiliation":[{"name":"Student Research Committee, Faculty of Medicine Shahid Beheshti University of Medical Sciences  Tehran Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hamed","family":"Rajaii","sequence":"additional","affiliation":[{"name":"West Nikan Hospital  Tehran Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-7707-946X","authenticated-orcid":false,"given":"Ali","family":"Goudarzi Karim","sequence":"additional","affiliation":[{"name":"Men's Health and Reproductive Health Research Center Shahid Beheshti University of Medical Sciences  Tehran Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,11,6]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.3390\/diagnostics12081892"},{"issue":"4","key":"e_1_2_13_3_1","first-page":"450","article-title":"Urachal Adenocarcinoma","volume":"4","author":"Pantuck A.
