However, rarely if ever are these atypical cells metastasis from other primary visceral malignancy due to \u201csac-like\u201d anatomic structure of this area. We present a case where these atypical cells were determined to be metastasis of gynecological origin by judicious use of immunohistochemical stains. A final diagnosis of serous tubal intraepithelial carcinoma of right fallopian tube was diagnosed only after total abdominal hysterectomy bilateral salpingo-oophorectomy. To our knowledge, this is the first report of a serous tubal intraepithelial carcinoma presenting as stage 4 colonic adenocarcinoma. The importance of this interesting case is 2-fold. It highlights the peritoneal cleft as an anatomic region not often recognized or discussed as well as tumor presentation in this region. In addition, this example stresses the need for additional mesothelial markers in addition to WT-1 workup of atypical mesothelial proliferation.<\/jats:p>","DOI":"10.1177\/1066896920988346","type":"journal-article","created":{"date-parts":[[2021,1,16]],"date-time":"2021-01-16T04:53:30Z","timestamp":1610772810000},"page":"506-509","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Atypical Cells in Peritoneal Cleft: A Pitfall in Diagnosis of Colorectal Adenocarcinoma"],"prefix":"10.1177","volume":"29","author":[{"given":"Whayoung","family":"Lee","sequence":"first","affiliation":[{"name":"University of California Irvine, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vishal Suresh","family":"Chandan","sequence":"additional","affiliation":[{"name":"University of California Irvine, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cary","family":"Johnson","sequence":"additional","affiliation":[{"name":"University of California Irvine, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2558-2583","authenticated-orcid":false,"given":"Xiaodong","family":"Li","sequence":"additional","affiliation":[{"name":"University of California Irvine, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,1,16]]},"reference":[{"key":"bibr1-1066896920988346","doi-asserted-by":"publisher","DOI":"10.5858\/arpa.2017-0475-RA"},{"key":"bibr2-1066896920988346","doi-asserted-by":"publisher","DOI":"10.1111\/his.13975"},{"key":"bibr3-1066896920988346","doi-asserted-by":"publisher","DOI":"10.1002\/ijc.28676"},{"key":"bibr4-1066896920988346","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21388"},{"key":"bibr5-1066896920988346","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2004.09.059"},{"key":"bibr6-1066896920988346","doi-asserted-by":"publisher","DOI":"10.1136\/jclinpath-2019-206056"},{"key":"bibr7-1066896920988346","doi-asserted-by":"publisher","DOI":"10.1007\/s00428-019-02663-0"},{"key":"bibr8-1066896920988346","doi-asserted-by":"publisher","DOI":"10.1038\/s41379-019-0344-3"},{"key":"bibr9-1066896920988346","doi-asserted-by":"publisher","DOI":"10.3390\/cancers3010164"},{"key":"bibr10-1066896920988346","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v20.i29.9850"},{"key":"bibr11-1066896920988346","first-page":"282","volume":"31","author":"Galanopoulos M","year":"2018","journal-title":"Ann Gastroenterol"},{"key":"bibr12-1066896920988346","volume-title":"Diagnostic Gynecologic and Obstetic Pathology: An Atlas and Text","author":"Reichert RA.","year":"2012","edition":"1"},{"key":"bibr13-1066896920988346","doi-asserted-by":"publisher","DOI":"10.1093\/jnci\/djx263"},{"key":"bibr14-1066896920988346","doi-asserted-by":"publisher","DOI":"10.1097\/01.pas.0000180854.28831.77"},{"key":"bibr15-1066896920988346","doi-asserted-by":"publisher","DOI":"10.3121\/cmr.2007.702"},{"key":"bibr16-1066896920988346","doi-asserted-by":"publisher","DOI":"10.1016\/j.ygyno.2009.01.013"},{"key":"bibr17-1066896920988346","doi-asserted-by":"publisher","DOI":"10.1016\/j.molonc.2009.01.004"},{"key":"bibr18-1066896920988346","doi-asserted-by":"publisher","DOI":"10.1002\/path.2091"}],"container-title":["International Journal of Surgical Pathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1066896920988346","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1066896920988346","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1066896920988346","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T10:21:39Z","timestamp":1777458099000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1066896920988346"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,1,16]]},"references-count":18,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2021,8]]}},"alternative-id":["10.1177\/1066896920988346"],"URL":"https:\/\/doi.org\/10.1177\/1066896920988346","relation":{},"ISSN":["1066-8969","1940-2465"],"issn-type":[{"value":"1066-8969","type":"print"},{"value":"1940-2465","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,1,16]]}}}
