Less than 75 cases have been reported worldwide. Here, we report a case of an asymptomatic carcinosarcoma of stomach in a lady in her 70\u2019s presenting incidentally who underwent distal gastrectomy with Billroth II reconstruction for a large epigastric mass along with a review of literature. Although carcinosarcoma in the stomach is a rare entity, it should be considered as a differential diagnosis in a rapidly growing gastric growth. It requires further descriptions and collections of individual cases.<\/jats:p>","DOI":"10.1136\/bcr-2023-255680","type":"journal-article","created":{"date-parts":[[2023,10,10]],"date-time":"2023-10-10T12:46:15Z","timestamp":1696941975000},"page":"e255680","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Asymptomatic giant gastric carcinosarcoma"],"prefix":"10.1136","volume":"16","author":[{"given":"Hitesh","family":"Sarda","sequence":"first","affiliation":[{"name":"Department of Surgical Gastroenterology, Dr Ram Manohar Lohia Institute of Medical Sciences, Lucknow, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anshuman","family":"Pandey","sequence":"additional","affiliation":[{"name":"Department of Surgical Gastroenterology, Dr Ram Manohar Lohia Institute of Medical Sciences, Lucknow, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abhishek","family":"Gatuam","sequence":"additional","affiliation":[{"name":"Department of Surgical Gastroenterology, Dr Ram Manohar Lohia Institute of Medical Sciences, Lucknow, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hareesh Shanthappa","family":"Nellikoppad","sequence":"additional","affiliation":[{"name":"Department of Surgical Gastroenterology, Dr Ram Manohar Lohia Institute of Medical Sciences, Lucknow, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2023,10,10]]},"reference":[{"key":"2025082712514698000_16.10.e255680.1","doi-asserted-by":"crossref","DOI":"10.1186\/s13000-020-01037-4","article-title":"Early-stage Multidifferentiated gastric Carcinosarcoma and post-resection local recurrence: a case report","volume":"15","author":"Shioya","year":"2020","journal-title":"Diagn Pathol"},{"key":"2025082712514698000_16.10.e255680.2","doi-asserted-by":"crossref","first-page":"135","DOI":"10.5144\/0256-4947.1999.135","article-title":"Sarcomatoid carcinoma of the stomach with heterologous elements","volume":"19","author":"Khan","year":"1999","journal-title":"Ann Saudi Med"},{"key":"2025082712514698000_16.10.e255680.3","doi-asserted-by":"crossref","first-page":"416","DOI":"10.1177\/030089160809400320","article-title":"Carcinosarcoma of the Esophagogastric junction","volume":"94","author":"Solerio","year":"2008","journal-title":"Tumori"},{"key":"2025082712514698000_16.10.e255680.4","doi-asserted-by":"crossref","first-page":"682","DOI":"10.5858\/2000-124-0682-SOOEAS","article-title":"Synchronous occurrence of epithelial and Stromal tumors in the stomach: a report of 6 cases","volume":"124","author":"Maiorana","year":"2000","journal-title":"Arch Pathol Lab Med"},{"key":"2025082712514698000_16.10.e255680.5","doi-asserted-by":"crossref","first-page":"93","DOI":"10.1016\/S0344-0338(99)80077-6","article-title":"A case report of gastric Carcinosarcoma with Rhabdomyosarcomatous and Neuroendocrinal differentiation","volume":"195","author":"Tsuneyama","year":"1999","journal-title":"Pathol Res Pract"},{"key":"2025082712514698000_16.10.e255680.6","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9610(67)90325-X"},{"key":"2025082712514698000_16.10.e255680.7","unstructured":"Quekenstadt H .
