Here, we present computed tomography (CT) scans and endoscopic ultrasound (EUS) images from a 71-year-old Taiwanese man newly diagnosed with colonic adenocarcinoma. CT examination revealed a mural nodule in the proximal jejunum, with good enhancement after IV contrast medium administration. Push enteroscopy was performed to localize the lesion and evaluate its nature, and a 1 cm subepithelial lesion was found. The lesion appeared hyperechoic within the submucosal layer of the bowel wall on endoscopic ultrasound examination. A tattoo was performed, and the lesion was removed during the resection of colon cancer. The histopathology confirmed the presence of pancreatic tissue inside. As far as we know, this is the first description in the literature of an endoscopic ultrasound finding of a jejunal ectopic pancreas.<\/jats:p>","DOI":"10.3390\/diagnostics13040660","type":"journal-article","created":{"date-parts":[[2023,2,10]],"date-time":"2023-02-10T04:48:03Z","timestamp":1676004483000},"page":"660","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Endoscopic Ultrasound Appearance of Jejunal Ectopic Pancreas Mimicking Metastatic Nodule in a Cancer Patient"],"prefix":"10.3390","volume":"13","author":[{"given":"Chien-Wei","family":"Lee","sequence":"first","affiliation":[{"name":"Division of Gastroenterology, Changhua Christian Hospital, Changhua 500, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7094-1170","authenticated-orcid":false,"given":"Yen-Chih","family":"Lin","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Changhua Christian Hospital, Changhua 500, Taiwan"},{"name":"College of Medicine, National Chung Hsing University, Taichung 400, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui-Ting","family":"Hsu","sequence":"additional","affiliation":[{"name":"Department of Surgical Pathology, Changhua Christian Hospital, Changhua 500, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5936-7112","authenticated-orcid":false,"given":"Yang-Yuan","family":"Chen","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Changhua Christian Hospital, Changhua 500, Taiwan"},{"name":"College of Medicine, National Chung Hsing University, Taichung 400, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3494-2245","authenticated-orcid":false,"given":"Hsu-Heng","family":"Yen","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Changhua Christian Hospital, Changhua 500, Taiwan"},{"name":"College of Medicine, National Chung Hsing University, Taichung 400, Taiwan"},{"name":"Department of Electrical Engineering, Chung Yuan Christian University, Taoyuan 320, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"281","DOI":"10.12998\/wjcc.v4.i9.281","article-title":"Cystic jejunal duplication with Heinrich\u2019s type I ectopic pancreas, incidentally discovered in a patient with pancreatic tail neoplasm","volume":"4","author":"Gurzu","year":"2016","journal-title":"World J.
