Although endometriosis is a benign condition, malignant transformation of endometriosis is a well-described phenomenon. Malignancies arising in endometriosis are uncommon at extragonadal pelvic sites. A case of endometrioid adenocarcinoma in the native ureter of a postmenopausal renal transplant patient presented with painless gross hematuria and hydroureteronephrosis. The patient had a history of total abdominal hysterectomy and bilateral salpingo-oophrectomy 14 years prior for menorrhagia and had since been on unopposed estrogen replacement therapy. Workup revealed a filling defect in the native left mid-ureter secondary to a large 2.5-cm ureteral tumor. Endoscopic biopsies of the native left ureteral mass showed endometrioid adenocarcinoma, grade II-III. The patient ultimately underwent an open native left nephroureterectomy and temporary diverting colostomy. Final pathology confirmed endometrioid adenocarcinoma, grade II-III, arising in a background of endometriosis with negative perirectal lymph nodes. This case of ureteral endometrioid adenocarcinoma highlights the importance of obtaining a careful history and maintaining a high index of suspicion for malignant degeneration, especially in the context of hyperestrogenism.<\/jats:p>","DOI":"10.1100\/tsw.2010.166","type":"journal-article","created":{"date-parts":[[2011,8,15]],"date-time":"2011-08-15T09:32:08Z","timestamp":1313400728000},"page":"1714-1722","source":"Crossref","is-referenced-by-count":7,"title":["Endometrioid Adenocarcinoma in the Native Ureter of a Renal Transplant Patient: Case Report and Review of the Literature"],"prefix":"10.1100","volume":"10","author":[{"given":"Kelly A.","family":"Healy","sequence":"first","affiliation":[{"name":"Department of Urology Emory, University School of Medicine, Atlanta, GA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenneth J.","family":"Carney","sequence":"additional","affiliation":[{"name":"Department of Urology Emory, University School of Medicine, Atlanta, GA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adeboye O.","family":"Osunkoya","sequence":"additional","affiliation":[{"name":"Department of Urology Emory, University School of Medicine, Atlanta, GA, USA"},{"name":"Department of Pathology Emory, University School of Medicine, Atlanta, GA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"98","container-title":["The Scientific World JOURNAL"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/tswj\/2010\/182610.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/tswj\/2010\/182610.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,8,23]],"date-time":"2016-08-23T07:13:47Z","timestamp":1471936427000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/tswj\/2010\/182610\/abs\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010]]},"references-count":0,"alternative-id":["182610"],"URL":"https:\/\/doi.org\/10.1100\/tsw.2010.166","relation":{},"ISSN":["1537-744X"],"issn-type":[{"value":"1537-744X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010]]}}}
