The presence of H. pylori should be confirmed via special stains and\/or immunohistochemistry of gastric biopsies from multiple anatomic sites of the stomach. Mucosa-associated lymphoid tissue lymphoma is diagnosed with histopathologic examination and positive immunohistochemical staining for certain B-cell markers. Ancillary testing should be performed to determine any genetic abnormalities in H. pylori that increases its virulence. We report the case of a 49-year-old woman with recurrent epigastric pain and vomiting found to have chronic H. pylori gastritis despite appropriate rounds of treatment with first-line therapy. She was diagnosed with mucosa-associated lymphoid tissue lymphoma via histopathologic examination. She ultimately required oncological treatment due to H. pylori infection refractory to antibiotic treatment. <\/jats:p>","DOI":"10.1177\/2050313x19869473","type":"journal-article","created":{"date-parts":[[2019,8,17]],"date-time":"2019-08-17T07:23:00Z","timestamp":1566026580000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Gastric MALT lymphoma refractory to <i>Helicobacter pylori<\/i> antibiotic therapy"],"prefix":"10.1177","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2446-4996","authenticated-orcid":false,"given":"Charlene L","family":"Rohm","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, WellStar Kennestone Hospital, Marietta, GA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sara","family":"Acree","sequence":"additional","affiliation":[{"name":"Department of Pathology, WellStar Kennestone Hospital, Marietta, GA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,8,17]]},"reference":[{"key":"bibr1-2050313X19869473","doi-asserted-by":"publisher","DOI":"10.1182\/blood.V89.11.3909"},{"key":"bibr2-2050313X19869473","doi-asserted-by":"publisher","DOI":"10.1016\/0140-6736(91)92035-Z"},{"key":"bibr3-2050313X19869473","doi-asserted-by":"publisher","DOI":"10.1136\/gut.49.3.347"},{"key":"bibr4-2050313X19869473","doi-asserted-by":"publisher","DOI":"10.1038\/sj.bjc.6603517"},{"key":"bibr5-2050313X19869473","doi-asserted-by":"publisher","DOI":"10.1093\/jnci\/djs003"},{"key":"bibr6-2050313X19869473","doi-asserted-by":"publisher","DOI":"10.1016\/S0091-679X(04)75027-X"},{"key":"bibr7-2050313X19869473","doi-asserted-by":"publisher","DOI":"10.1182\/blood.V93.11.3601"},{"key":"bibr8-2050313X19869473","doi-asserted-by":"publisher","DOI":"10.1038\/sj.leu.2403501"},{"key":"bibr9-2050313X19869473","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2003.08.033"},{"key":"bibr10-2050313X19869473","doi-asserted-by":"publisher","DOI":"10.1016\/j.cgh.2009.07.017"},{"key":"bibr11-2050313X19869473","doi-asserted-by":"publisher","DOI":"10.1136\/gut.2010.224949"},{"key":"bibr12-2050313X19869473","unstructured":"NCCN clinical practice guidelines in oncology (NCCN guidelines) (version 1): B-cell lymphomas (version 2), https:\/\/www.nccn.org\/professionals\/physician_gls\/pdf\/b-cell.pdf"}],"container-title":["SAGE Open Medical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2050313X19869473","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/2050313X19869473","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2050313X19869473","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,2]],"date-time":"2025-03-02T09:07:25Z","timestamp":1740906445000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/2050313X19869473"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,1]]},"references-count":12,"alternative-id":["10.1177\/2050313X19869473"],"URL":"https:\/\/doi.org\/10.1177\/2050313x19869473","relation":{},"ISSN":["2050-313X","2050-313X"],"issn-type":[{"value":"2050-313X","type":"print"},{"value":"2050-313X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,1]]},"article-number":"2050313X19869473"}}
