She had undergone hysterectomy and bilateral salpingo-oophorectomy to treat clear cell endometrial carcinoma 10 months before the presentation. She was anaemic and tachycardic; abdominal CT scan revealed a large duodenal mass. Her gastrointestinal bleed was not amenable to endoscopic intervention, so she had emergent laparotomy, pancreaticoduodenectomy with duodenal mass excision. Histopathology confirmed that the duodenal mass was a metastatic deposit from her clear cell endometrial cancer. Postoperatively, she was frail and chose hospice care and she died 90 days postoperatively. Clear cell endometrial cancer is a rare subtype of endometrial cancer, that has a worse prognosis compared with the more common endometrioid subtype. The duodenum is a rare site for metastatic endometrial cancer, and we report this case to alert clinicians to the possibility of metastases to the small intestine in patients with clear cell endometrial cancer.<\/jats:p>","DOI":"10.1136\/bcr-2020-235051","type":"journal-article","created":{"date-parts":[[2020,6,12]],"date-time":"2020-06-12T05:59:32Z","timestamp":1591941572000},"page":"e235051","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Metastatic clear cell endometrial carcinoma: an unusual cause of a common clinical presentation"],"prefix":"10.1136","volume":"13","author":[{"given":"Oluwadunni","family":"Emiloju","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Albert Einstein Medical Center, Philadelphia, Pennsylvania, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nellowe","family":"Candelario","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Albert Einstein Medical Center, Philadelphia, Pennsylvania, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudia","family":"Dourado","sequence":"additional","affiliation":[{"name":"Hematology Oncology Department, Albert Einstein Medical Center, Philadelphia, Pennsylvania, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2020,6,11]]},"reference":[{"key":"2025082804015893000_13.6.e235051.1","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21551"},{"key":"2025082804015893000_13.6.e235051.2","doi-asserted-by":"crossref","first-page":"46","DOI":"10.1177\/107327480901600107","article-title":"Non-endometrioid adenocarcinoma of the uterine corpus: a review of selected histological subtypes","volume":"16","author":"Mendivil","year":"2009","journal-title":"Cancer Control"},{"key":"2025082804015893000_13.6.e235051.3","doi-asserted-by":"publisher","DOI":"10.1016\/0090-8258(83)90111-7"},{"key":"2025082804015893000_13.6.e235051.4","doi-asserted-by":"publisher","DOI":"10.1097\/00125480-200205000-00001"},{"key":"2025082804015893000_13.6.e235051.5","doi-asserted-by":"crossref","first-page":"1719","DOI":"10.1002\/ijc.31961","article-title":"Risk factors for endometrial cancer: an umbrella review of the literature","volume":"145","author":"Raglan","year":"2019","journal-title":"Int J Cancer"},{"key":"2025082804015893000_13.6.e235051.6","doi-asserted-by":"publisher","DOI":"10.1097\/IGC.0000000000000844"},{"key":"2025082804015893000_13.6.e235051.7","unstructured":"National Comprehensive Cancer Network .
