Despite a thorough history, physical examination and complete diagnostic workup, the correct diagnosis of small intestinal neoplasm has been established preoperatively in only 50% of cases. Due to the rarity of this disease, there are very few established guidelines for its management and it has been primarily treated the same way as colorectal cancer, even though patient\u2019s prognostic outcome is worse. With new guidelines in 2020, we review a clinical case of a 64-year-old male patient with adenocarcinoma of the jejunum treated in our institution.<\/jats:p>","DOI":"10.1093\/jscr\/rjab124","type":"journal-article","created":{"date-parts":[[2021,3,13]],"date-time":"2021-03-13T04:13:24Z","timestamp":1615608804000},"source":"Crossref","is-referenced-by-count":4,"title":["Adenocarcinoma of the jejunum: management of a rare small bowel neoplasm"],"prefix":"10.1093","volume":"2021","author":[{"given":"Raquel","family":"Pereira","sequence":"first","affiliation":[{"name":"General Surgery Department, Tondela-Viseu Hospital Centre, Viseu, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andr\u00e9","family":"Tojal","sequence":"additional","affiliation":[{"name":"General Surgery Department, Tondela-Viseu Hospital Centre, Viseu, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aline","family":"Gomes","sequence":"additional","affiliation":[{"name":"General Surgery Department, Tondela-Viseu Hospital Centre, Viseu, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos","family":"Casimiro","sequence":"additional","affiliation":[{"name":"General Surgery Department, Tondela-Viseu Hospital Centre, Viseu, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sara","family":"Moreira","sequence":"additional","affiliation":[{"name":"Oncology Department, Tondela-Viseu Hospital Centre, Viseu, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fortunato","family":"Vieira","sequence":"additional","affiliation":[{"name":"Pathology Department, Histocit Laboratory, Trofa, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pedro","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"Pathology Department, Tondela-Viseu Hospital Centre, Viseu, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2021,4,22]]},"reference":[{"key":"2021070811402095000_ref1","doi-asserted-by":"crossref","first-page":"15","DOI":"10.1016\/j.dld.2017.09.123","article-title":"Small bowel adenocarcinoma: French intergroup clinical practice guidelines for diagnosis, treatments and follow-up (SNFGE, FFCD, GERCOR, UNICANCER, SFCD, SFED, SFRO)","volume":"50","author":"Locher","year":"2018","journal-title":"Dig Liver Dis"},{"key":"2021070811402095000_ref2","doi-asserted-by":"crossref","first-page":"177","DOI":"10.1186\/s12957-016-0932-3","article-title":"Small bowel adenocarcinoma of the jejunum: a case report and literature review","volume":"14","author":"Li","year":"2016","journal-title":"World J Surg Oncol"},{"key":"2021070811402095000_ref3","first-page":"1","article-title":"Adenocarcinoma of jejunum","volume":"8","author":"Rongviriyapanich","year":"2018","journal-title":"J Surg Case Rep"},{"key":"2021070811402095000_ref4","doi-asserted-by":"crossref","first-page":"1417","DOI":"10.1016\/j.ejca.2011.10.038","article-title":"Incidence, prevalence and survival of patients with rare epithelial digestive cancers diagnosed in Europe in 1995\u20132002","volume":"48","author":"Faivre","year":"2012","journal-title":"Eur J Cancer"},{"key":"2021070811402095000_ref5","doi-asserted-by":"crossref","first-page":"1109","DOI":"10.6004\/jnccn.2019.0043","article-title":"Small bowel adenocarcinoma, version 1.2020, NCCN clinical practice guidelines in oncology","volume":"17","author":"Benson","year":"2019","journal-title":"J Natl Compr Canc Netw"},{"key":"2021070811402095000_ref6","doi-asserted-by":"crossref","first-page":"132","DOI":"10.1016\/j.ijsu.2018.10.028","article-title":"For the SCARE group.
