In the cases where the gastrointestinal tract is implicated, the more frequent localizations involve the small bowel, especially the duodenum. A case of a 67-year-old man who underwent clinical investigation after presenting with a progressive weight loss and showing a hypercapting right paracoeliac adenopathy at PET-CT scan is reported herein. A gastroscopy and a colonoscopy were done. The biopsies of the endoscopically normal ileal mucosa encompassed some submucosal Peyer\u2019s patches. Histological examination of this lymphoid tissue revealed several foamy macrophages which turned out positive on periodic acid-Schiff special staining. Polymerase chain reaction of the microdissected lymph follicles allowed for confirming Whipple\u2019s disease diagnosis. A targeted antibiotic treatment administrated to the patient led to a rapid clinical improvement. This finding of a previously unreported localization of infected macrophages in Whipple\u2019s disease suggests that sampling the organized mucosal-submucosal lymphoid tissue may increase the diagnostic yield in endoscopic biopsies.<\/jats:p>","DOI":"10.1155\/2019\/1509745","type":"journal-article","created":{"date-parts":[[2019,6,23]],"date-time":"2019-06-23T19:30:34Z","timestamp":1561318234000},"page":"1-4","source":"Crossref","is-referenced-by-count":1,"title":["Whipple\u2019s Disease Affecting Ileal Peyer\u2019s Patches: The First Case Report"],"prefix":"10.1155","volume":"2019","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2360-3352","authenticated-orcid":true,"given":"Sabah","family":"Sid\u2019Amar","sequence":"first","affiliation":[{"name":"Department of Clinical Pathology, Promed SA, Medical Laboratory, Marly\/Fribourg, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2034-5431","authenticated-orcid":true,"given":"Giacomo","family":"Puppa","sequence":"additional","affiliation":[{"name":"Department of Clinical Pathology, Geneva University Hospital, Geneva, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/j.micinf.2010.08.001"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0b013e3181f204a8"},{"issue":"2","key":"3","first-page":"S10","volume":"31","year":"1999","journal-title":"Endoscopy"},{"issue":"3","key":"4","first-page":"167","volume":"30","year":"2014","journal-title":"Viszeralmedizin: Gastrointestinal Medicine and Surgery"},{"issue":"3","key":"5","first-page":"392","volume":"73","year":"2010","journal-title":"Acta Gastro-Enterologica Belgica"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(14)61043-6"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1128\/CVI.13.2.170-178.2006"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1055\/s-0041-100846"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1016\/j.jinf.2014.05.008"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.2217\/fmb.12.124"},{"issue":"4","key":"11","first-page":"117","volume":"34","year":"2013","journal-title":"Giornale di Chirurgia"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1159\/000233288"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1111\/apt.13140"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/S0016-5107(97)70098-1"},{"issue":"7","key":"15","volume":"5","year":"2018","journal-title":"Open Forum Infectious Diseases"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000000714"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijid.2018.08.003"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1016\/S1473-3099(15)00537-X"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1309\/7678-E2DW-HFJ5-QYUJ"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.4061\/2010\/823710"}],"container-title":["Case Reports in Pathology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cripa\/2019\/1509745.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cripa\/2019\/1509745.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cripa\/2019\/1509745.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,6,23]],"date-time":"2019-06-23T19:30:43Z","timestamp":1561318243000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/cripa\/2019\/1509745\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,6,23]]},"references-count":20,"alternative-id":["1509745","1509745"],"URL":"https:\/\/doi.org\/10.1155\/2019\/1509745","relation":{},"ISSN":["2090-6781","2090-679X"],"issn-type":[{"value":"2090-6781","type":"print"},{"value":"2090-679X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,6,23]]}}}
