Neoplasms arising from the uterine corpus that are morphologically and immunohistochemically similar to true mesonephric carcinomas, but do not arise from mesonephric remnants, are termed \u201cmesonephric\u2010like\u201d adenocarcinomas. The diagnosis of mesonephric\u2010like adenocarcinoma is pathologically challenging. These tumors often exhibit a mixture of morphologic patterns of more common adenocarcinomas. Although their morphologic, immunohistochemical, and molecular profiles have been recently defined, much remains unknown about mesonephric\u2010like adenocarcinomas. A better understanding of mesonephric\u2010like andenocarcinoma\u2019s pathogenesis and molecular classification is needed to improve diagnosis and guide management of this rare and aggressive subtype of endometrial cancer. An updated International Federation of Gynecology and Obstetrics (FIGO) staging system for endometrial carcinoma was introduced in June 2023, upstaging aggressive histological subtypes such as mesonephric\u2010like adenocarcinoma. In this report, we describe a patient with mesonephric\u2010like adenocarcinoma arising in the uterine corpus, highlight the clinical significance of 2023 FIGO restaging, and discuss the multidisciplinary approach to treatment.<\/jats:p>","DOI":"10.1155\/crog\/9935815","type":"journal-article","created":{"date-parts":[[2026,5,9]],"date-time":"2026-05-09T23:05:01Z","timestamp":1778367901000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Mesonephric\u2010Like Adenocarcinoma of the Endometrium and the Impact of the Updated 2023 FIGO Staging System"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6961-5914","authenticated-orcid":false,"given":"Joy","family":"Ogunmuyiwa","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-3193-007X","authenticated-orcid":false,"given":"Alexandra","family":"Hamilton","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0477-1473","authenticated-orcid":false,"given":"Judy","family":"Hayek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-6668-8167","authenticated-orcid":false,"given":"Jocelyn","family":"Ogunmuyiwa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0653-8384","authenticated-orcid":false,"given":"Constantine","family":"Gorelick","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4286-2664","authenticated-orcid":false,"given":"Daniel","family":"Levitan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1249-6915","authenticated-orcid":false,"given":"Hani","family":"Ashamalla","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,5,9]]},"reference":[{"key":"e_1_2_11_1_2","doi-asserted-by":"publisher","DOI":"10.1002\/cncy.22160"},{"key":"e_1_2_11_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0000000000000991"},{"key":"e_1_2_11_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0000000000001401"},{"key":"e_1_2_11_4_2","doi-asserted-by":"publisher","DOI":"10.1111\/his.12895"},{"key":"e_1_2_11_5_2","doi-asserted-by":"publisher","DOI":"10.3390\/jcm10040698"},{"key":"e_1_2_11_6_2","doi-asserted-by":"publisher","DOI":"10.3390\/biomedicines11082269"},{"key":"e_1_2_11_7_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00432-019-03123-7"},{"key":"e_1_2_11_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/ijgo.14923"},{"key":"e_1_2_11_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ygyno.2017.02.004"},{"key":"e_1_2_11_10_2","doi-asserted-by":"crossref","first-page":"804","DOI":"10.1111\/his.15302","article-title":"Endometrial Carcinoma Staging: A Comparison to FIGO 2009 Staging in the Setting of Known and Unknown Molecular Classification","volume":"85","author":"Libert D.","year":"2023","journal-title":"Histopathology"},{"key":"e_1_2_11_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejso.2025.109695"},{"key":"e_1_2_11_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ygyno.2025.09.015"},{"key":"e_1_2_11_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(18)30079-2"},{"key":"e_1_2_11_14_2","article-title":"NCCN Guidelines\u00ae Insights: Uterine Neoplasms, Version 3.2025","volume":"23","author":"Abu-Rustum N.
