The patient was diagnosed with epithelial cell carcinoma of the bladder and underwent resection of the bladder, the right ureter and right kidney two years ago. One and a half years later, the enhanced CT examination revealed diffuse thickening of the stomach. Gastroscopy showed the gastric mucosa were swollen, congested and stiff. The biopsy of the EUS-FNA (Endoscopic Ultrasound-Guided Fine Needle Aspiration) showed a high likelihood of bladder epithelial tumors. Then the patient underwent a total gastrectomy and immunohistochemistry of the specimen indicated that her tumor tissue was originated from the bladder. We recommend that clinicians remain vigilant for gastric tumors that are metastases from bladder cancer, especially in patients with a previous primary bladder tumor.<\/jats:p>","DOI":"10.3389\/fonc.2025.1591475","type":"journal-article","created":{"date-parts":[[2025,7,3]],"date-time":"2025-07-03T04:10:19Z","timestamp":1751515819000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Case Report: A patient with metastatic bladder cancer in the stomach"],"prefix":"10.3389","volume":"15","author":[{"given":"Shurong","family":"Liu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junling","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,7,3]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1093\/ajcp\/aqab202","article-title":"Metastatic neoplasms involving the stomach","volume":"157","author":"Vyas","year":"2022","journal-title":"Am J Clin Pathol"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1007\/s00595-013-0671-9","article-title":"Clinicopathological features and treatment outcomes of metastatic tumors in the stomach","volume":"44","author":"Namikawa","year":"2014","journal-title":"Surg Today"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.05.0095","article-title":"Bloodborne metastatic tumors to the gastrointestinal tract: CT findings with clinicopathologic correlation","volume":"186","author":"Kim","year":"2006","journal-title":"AJR Am J Roentgenol"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(22)01188-6","article-title":"Current best practice for bladder cancer: a narrative review of diagnostics and treatments","volume":"400","author":"Comp\u00e9rat","year":"2022","journal-title":"Lancet"},{"key":"B5","doi-asserted-by":"publisher","first-page":"69","DOI":"10.1159\/000030361","article-title":"Patterns of metastasis in muscle-invasive bladder cancer (pT2-4): An autopsy study on 367 patients","volume":"62","author":"Wallmeroth","year":"1999","journal-title":"Urol Int"},{"key":"B6","article-title":"An autopsy case of untreated bladder cancer","volume":"33","author":"Pak","year":"1987","journal-title":"Hinyokika Kiyo"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.3348\/kjr.2009.10.6.645","article-title":"Metastatic gastric linitis plastica from bladder cancer mimicking a primary gastric carcinoma: a case report","volume":"10","author":"Hong","year":"2009","journal-title":"Korean J Radiol"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1016\/j.clgc.2015.09.001","article-title":"Case report of a rare presentation of urothelial carcinoma with gastric metastasis","volume":"14","author":"Wymer","year":"2016","journal-title":"Clin Genitourin Cancer"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1177\/10668969231160257","article-title":"Ureteral metastasis of colonic adenocarcinoma with enteroblastic differentiation: A rare case to be distinguished from clear cell adenocarcinoma of the urinary tract","volume":"31","author":"Minato","year":"2023","journal-title":"Int J Surg Pathol"},{"key":"B10","doi-asserted-by":"publisher","first-page":"90","DOI":"10.1186\/s12894-025-01783-x","article-title":"Spectral CT findings of bladder urothelial carcinoma with gastric metastasis: a case report","volume":"25","author":"Wang","year":"2025","journal-title":"BMC Urol"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1106106","article-title":"Radiotherapy with or without chemotherapy in muscle-invasive bladder cancer","volume":"366","author":"James","year":"2012","journal-title":"N Engl J Med"}],"container-title":["Frontiers in Oncology"],"original-title":[],"link":[{"URL":"https:\/\/www.frontiersin.org\/articles\/10.3389\/fonc.2025.1591475\/full","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,7,3]],"date-time":"2025-07-03T04:10:23Z","timestamp":1751515823000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.frontiersin.org\/articles\/10.3389\/fonc.2025.1591475\/full"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,7,3]]},"references-count":11,"alternative-id":["10.3389\/fonc.2025.1591475"],"URL":"https:\/\/doi.org\/10.3389\/fonc.2025.1591475","relation":{},"ISSN":["2234-943X"],"issn-type":[{"value":"2234-943X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,7,3]]},"article-number":"1591475"}}
