We report a case of primary esophageal MALT lymphoma that was successfully treated by endoscopic submucosal dissection (ESD). A 70\u2010year\u2010old woman presented with an elevated lesion in the lower esophagus that was detected incidentally on computed tomography. Endoscopy and endoscopic ultrasonography revealed a subepithelial lesion confined to the submucosal layer without apparent invasion of the muscularis propria. Although an endoscopic biopsy suggested a low\u2010grade lymphoma, a definitive diagnosis could not be established because of the limited tissue volume. Therefore, ESD was performed to obtain an adequate specimen for definitive diagnosis, and complete resection was achieved as a result. Histopathological and immunohistochemical examinations of the resected specimen confirmed primary esophageal MALT lymphoma. The patient has remained in complete remission for 3 years without additional therapy. This case suggests that ESD may be a diagnostic and therapeutic option for primary esophageal MALT lymphoma.<\/jats:p>\n                  <jats:p>\n                    <jats:bold>Trial Registration<\/jats:bold>\n                    : N\/A.\n                  <\/jats:p>","DOI":"10.1002\/deo2.70384","type":"journal-article","created":{"date-parts":[[2026,7,16]],"date-time":"2026-07-16T18:53:06Z","timestamp":1784227986000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Successful Endoscopic Submucosal Dissection for Primary Esophageal Mucosa\u2010Associated Lymphoid Tissue Lymphoma"],"prefix":"10.1002","volume":"7","author":[{"given":"Junya","family":"Makiyama","sequence":"first","affiliation":[{"name":"Department of Hematology Sasebo City General Hospital Nagasaki Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroko","family":"Fukuda","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Sasebo City General Hospital Nagasaki Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyoko","family":"Minamino","sequence":"additional","affiliation":[{"name":"Department of Hematology Sasebo City General Hospital Nagasaki Japan"},{"name":"Department of Hematology Nagasaki University Hospital  Nagasaki Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yukiyoshi","family":"Moriuchi","sequence":"additional","affiliation":[{"name":"Department of Hematology Sasebo City General Hospital Nagasaki Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koichi","family":"Ohshima","sequence":"additional","affiliation":[{"name":"Department of Pathology Kurume University School of Medicine Fukuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,16]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41375\u2010022\u201001620\u20102"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.annonc.2019.10.010"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.annonc.a058869"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1182\/blood\u20102017\u201003\u2010771915"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/1097\u20100142(19800701)46:1<215::aid\u2010cncr2820460136>3.0.co;2\u20106"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.7759\/cureus.17628"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000006478"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1055\/a\u20101722\u20102386"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.lrr.2016.12.001"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/den.12138"}],"container-title":["DEN Open"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/deo2.70384","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/deo2.70384","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/deo2.70384","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,16]],"date-time":"2026-07-16T18:53:07Z","timestamp":1784227987000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/deo2.70384"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,16]]},"references-count":10,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2027,4]]}},"alternative-id":["10.1002\/deo2.70384"],"URL":"https:\/\/doi.org\/10.1002\/deo2.70384","archive":["Portico"],"relation":{},"ISSN":["2692-4609","2692-4609"],"issn-type":[{"value":"2692-4609","type":"print"},{"value":"2692-4609","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,7,16]]},"assertion":[{"value":"2026-04-19","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-07-06","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-07-16","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e70384"}}
