He had sustained chest injuries and a grade 1 splenic laceration. He had a moderate amount of free fluid and some omental standing on trauma CT, which was concerning for occult malignancy. A follow-up CT 4\u2005weeks later showed a marked progression of the ascites and omental stranding. Ascitic tap was negative for malignancy. Tumour markers were normal. The patient developed a proximal small bowel obstruction which appeared to be related to this omental caking in the left\u00a0upper quadrant on CT. Gastroduodenoscopy did not display any mass lesion. There was an external compression of the duodenum which could not be traversed with the scope. Laparoscopy showed a widespread peritoneal carcinomatosis. Biopsies of the omentum and peritoneum confirmed metastatic signet ring cell carcinoma (cytokeratin 7 and cytokeratin 20 positive). The patient was palliated but died 2\u2005weeks after his diagnosis.<\/jats:p>","DOI":"10.1136\/bcr-2013-203407","type":"journal-article","created":{"date-parts":[[2014,2,17]],"date-time":"2014-02-17T12:03:00Z","timestamp":1392638580000},"page":"bcr2013203407","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Metastatic signet ring cell carcinoma of unknown primary source"],"prefix":"10.1136","volume":"2014","author":[{"given":"Dermot","family":"O'Kane","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kylie","family":"Dean","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rachael","family":"Nightingale","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Simone","family":"Carlotto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2014,2,17]]},"reference":[{"key":"2025042702394942000_2014.feb17_1.bcr2013203407.1","doi-asserted-by":"publisher","DOI":"10.1136\/jcp.50.10.867"},{"key":"2025042702394942000_2014.feb17_1.bcr2013203407.2","doi-asserted-by":"publisher","DOI":"10.4065\/mcp.2010.0463"},{"key":"2025042702394942000_2014.feb17_1.bcr2013203407.3","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v19.i24.3895"},{"key":"2025042702394942000_2014.feb17_1.bcr2013203407.4","doi-asserted-by":"publisher","DOI":"10.4103\/0970-9371.117646"},{"key":"2025042702394942000_2014.feb17_1.bcr2013203407.5","doi-asserted-by":"crossref","first-page":"768","DOI":"10.5489\/cuaj.630","article-title":"Primary signet ring cell carcinoma of the prostate","volume":"7","author":"Kwon","year":"2013","journal-title":"Can Urol Assoc J"},{"key":"2025042702394942000_2014.feb17_1.bcr2013203407.6","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.14.2118"},{"key":"2025042702394942000_2014.feb17_1.bcr2013203407.7","doi-asserted-by":"publisher","DOI":"10.1245\/s10434-009-0536-z"},{"key":"2025042702394942000_2014.feb17_1.bcr2013203407.8","doi-asserted-by":"publisher","DOI":"10.1093\/annonc\/mdr279"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2013-203407","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,27]],"date-time":"2025-04-27T09:39:56Z","timestamp":1745746796000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2013-203407"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,2,17]]},"references-count":8,"alternative-id":["10.1136\/bcr-2013-203407"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2013-203407","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2014,2,17]]}}}
