Gastric involvement by &lt;i&gt;Mycobacterium tuberculosis&lt;\/i&gt; is rare, especially when it occurs without other recognized infectious foci \u2013 primary gastric tuberculosis \u2013 with only a few reported cases. Endoscopic findings can be very heterogeneous, from areas of hyperemia to pseudotumor lesions. We present a case of primary gastric tuberculosis in an immunocompetent patient, in which the absence of an epidemiological context and nonspecific endoscopic findings led to a delay in the diagnosis. Bite-on-bite biopsies proved to be essential, allowing to obtain samples from deeper layers of the submucosa where &lt;i&gt;M. tuberculosis&lt;\/i&gt; was identified. This case aimed to increase awareness for this entity, especially in endemic countries or regions with a high prevalence of tuberculosis since the diagnosis is based mainly on a high index of suspicion. <\/jats:p>","DOI":"10.1159\/000531380","type":"journal-article","created":{"date-parts":[[2023,7,26]],"date-time":"2023-07-26T21:00:30Z","timestamp":1690405230000},"page":"191-195","source":"Crossref","is-referenced-by-count":2,"title":["Primary Gastric Tuberculosis in an Immunocompetent Patient: The Truth Lying beneath the Surface"],"prefix":"10.1159","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6395-3405","authenticated-orcid":false,"given":"F\u00e1bio Pereira","family":"Correia","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lu\u00edsa","family":"Martins Figueiredo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2643-9359","authenticated-orcid":false,"given":"Lu\u00eds Carvalho","family":"Louren\u00e7o","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sofia","family":"Santos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rita","family":"Theias Manso","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Horta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2023,7,26]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1128\/microbiolspec.tnmi7-0014-2016"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijtb.2018.10.004"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v20.i40.14831"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/S0377-1237(17)30568-3"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1080\/17474124.2020.1816823"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1177\/03000605211033189"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1186\/s12876-022-02171-7"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1007\/s12664-023-01343-x"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1186\/1471-230x-3-6"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1186\/s12876-020-1175-x"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.5946\/ce.2021.061"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.14309\/00000434-201710001-00192"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016\/j.rgmxen.2021.10.003"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.3109\/00365548.2014.974206"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1186\/s13256-015-0748-8"}],"container-title":["GE - Portuguese Journal of Gastroenterology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/pjg\/article-pdf\/31\/3\/191\/4236238\/000531380.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/pjg\/article-pdf\/31\/3\/191\/4236238\/000531380.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:34:14Z","timestamp":1745422454000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000531380"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,7,26]]},"references-count":15,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2024,6,4]]}},"URL":"https:\/\/doi.org\/10.1159\/000531380","archive":["Portico"],"relation":{},"ISSN":["2341-4545","2387-1954"],"issn-type":[{"value":"2341-4545","type":"print"},{"value":"2387-1954","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,7,26]]}}}
