Collision tumors have been reported in various organs, such as esophagus, stomach, colon, kidney, lung, skin, thyroid, breast, ovary and uterus. Uterine collision tumors of epithelial and mesenchymal origin are rare and often underrecognized. We report a rare concurrent occurrence of endometrial stromal sarcoma and endometrioid adenocarcinoma in a 65-year-old female. It is important to differentiate collision tumors from carcinosarcoma due to impact on clinical management and prognosis. Extensive gross sampling and careful morphological examination aided by immunohistochemical studies is necessary for the diagnosis of this rare entity. This case report aims to increase the awareness of this rare pathological entity with discussion on the management issue based on review of literature. This is the first case in Indian literature to the best of our knowledge.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/ijpm.ijpm_701_20","type":"journal-article","created":{"date-parts":[[2024,5,30]],"date-time":"2024-05-30T04:19:44Z","timestamp":1717042784000},"page":"802-805","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":9,"title":["Uterine collision tumor of endometrial stromal sarcoma and endometrioid adenocarcinoma"],"prefix":"10.4103","volume":"64","author":[{"given":"Shobhna","family":"Sharma","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nandini","family":"Vasdev","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Durgatosh","family":"Pandey","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R3-34-20240829","first-page":"5379","article-title":"Molecular evidence that most but not all carcinosarcomas of the uterus are combination tumors","volume":"57","author":"Wada","year":"1997","journal-title":"Cancer Res"},{"key":"R4-34-20240829","doi-asserted-by":"crossref","first-page":"1494","DOI":"10.1002\/1097-0142(19870415)59:8<1494::AID-CNCR2820590817>3.0.CO;2-V","article-title":"Immunocytochemical study of an endometrial diffuse clear cell stromal sarcoma and other endometrial stromal sarcomas","volume":"59","author":"Lifschitz Mercer","year":"1987","journal-title":"Cancer"},{"key":"R5-34-20240829","doi-asserted-by":"crossref","first-page":"666","DOI":"10.1097\/00000478-199506000-00007","article-title":"Carcinosarcomas of the female genital tract.
