These symptoms prompted a pelvic ultrasound and CT scan of the chest, abdomen and pelvis which showed a large 20\u2005cm left-sided adnexal mass. Following this imaging, blood tests revealed elevated tumour markers CA-125 and lactate dehydrogenase, resulting in referral to and surgical intervention by the gynaecology oncology team. Pathology and immunohistochemistry indicated that the tumour was a metastasis from the colon, that prompted for colonoscopy which confirmed that the carcinoma was a metastases from the sigmoid.<\/jats:p>","DOI":"10.1136\/bcr-2013-201055","type":"journal-article","created":{"date-parts":[[2013,11,25]],"date-time":"2013-11-25T08:15:18Z","timestamp":1385367318000},"page":"bcr2013201055","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["A colorectal carcinoma imitating a primary ovarian carcinoma in a postpartum woman"],"prefix":"10.1136","volume":"2013","author":[{"given":"Rohit","family":"Aiyer","sequence":"first","affiliation":[{"name":"Department of Obstetrics & Gynaecology, Royal Sussex County Hospital, East Sussex, Brighton, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kieran","family":"Sweetman","sequence":"additional","affiliation":[{"name":"Department of Obstetrics & Gynaecology, Royal Sussex County Hospital, East Sussex, Brighton, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Larsen-Disney","sequence":"additional","affiliation":[{"name":"Department of Obstetrics & Gynaecology, Royal Sussex County Hospital, East Sussex, Brighton, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Fish","sequence":"additional","affiliation":[{"name":"Department of Obstetrics & Gynaecology, Royal Sussex County Hospital, East Sussex, Brighton, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2013,11,25]]},"reference":[{"key":"2025082703212257000_2013.nov25_1.bcr2013201055.1","first-page":"209","article-title":"A case report of sigmoid colon cancer","volume":"2013","author":"Chang","year":"2010","journal-title":"Kawasaki Med J"},{"key":"2025082703212257000_2013.nov25_1.bcr2013201055.2","doi-asserted-by":"crossref","first-page":"158","DOI":"10.1186\/1752-1947-7-158","article-title":"Metastatic colorectal carcinoma mimicking primary ovarian carcinoma presenting as \u2018giant\u2019 ovarian tumors in an individual with probable Lynch syndrome: a case report","volume":"2013","author":"Ongom","year":"2013","journal-title":"J Med Case Rep"},{"key":"2025082703212257000_2013.nov25_1.bcr2013201055.3","doi-asserted-by":"crossref","first-page":"220","DOI":"10.3346\/jkms.2010.25.2.220","article-title":"Mucinous adenocarcinoma involving the ovary: comparative evaluation of the classification algorithms using tumor size and laterality","volume":"2013","author":"Jung","year":"2010","journal-title":"J Korean Med Sci"},{"key":"2025082703212257000_2013.nov25_1.bcr2013201055.4","doi-asserted-by":"crossref","first-page":"276","DOI":"10.1097\/PAS.0b013e31820508d0","article-title":"Ovarian metastases of pancreaticobiliary tract adenocarcinomas: analysis of 35 cases, with emphasis on the ability of metastases to simulate primary ovarian mucinous tumors","volume":"2013","author":"Meriden","year":"2011","journal-title":"Am J Surg Pathol"},{"key":"2025082703212257000_2013.nov25_1.bcr2013201055.5","first-page":"5","article-title":"Metastatic tumors of the ovary: the rate of incidence and the most frequent sites of primary tumors","volume":"2013","author":"Stanojevic","year":"2007","journal-title":"Acta Medica Medianae"},{"key":"2025082703212257000_2013.nov25_1.bcr2013201055.6","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1155\/2011\/612817","article-title":"Pathways of metastases from primary organs to the ovaries","volume":"2013","author":"Yamanisha","year":"2011","journal-title":"Obstet Gynecol Int"},{"key":"2025082703212257000_2013.nov25_1.bcr2013201055.7","doi-asserted-by":"crossref","first-page":"111","DOI":"10.1309\/G56H-97A2-JFMT-CD5N","article-title":"Ovarian metastases from colorectal carcinoma clinicopathologic profile, immunophenotype, and karyotype analysis","volume":"2013","author":"Dionigi","year":"2000","journal-title":"Am J Clin Pathol"},{"key":"2025082703212257000_2013.nov25_1.bcr2013201055.8","first-page":"8","article-title":"Ovarian cancer during pregnancy","volume":"2013","author":"Barut","year":"2011","journal-title":"J Pak Med Assoc"},{"key":"2025082703212257000_2013.nov25_1.bcr2013201055.9","unstructured":"Behtash N Zarchi M Gilani M .
