We present a case of MALT lymphoma with plasmacytic differentiation and amyloid deposition. Although plasmacytic differentiation is shown in some cases, amyloid deposition is the rare one in the current cases we collected. Amyloidosis is often associated with some malignant diseases, but MALT is known as an indolent lymphoma. We want to report this case to raise pathologists\u2019 cognizance on this disease.<\/jats:p>","DOI":"10.3389\/fonc.2026.1718760","type":"journal-article","created":{"date-parts":[[2026,3,5]],"date-time":"2026-03-05T05:25:25Z","timestamp":1772688325000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["A case of pulmonary mucosa-associated lymphoid tissue lymphoma with plasmacytic differentiation and amyloid deposition: case report and literature review"],"prefix":"10.3389","volume":"16","author":[{"given":"Zhihui","family":"Wang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoxi","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dingrong","family":"Zhong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,3,5]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1007\/s12105-022-01461-6","article-title":"Extranodal MALT lymphoma in the oral cavity: A series of three cases with review of literature","volume":"16","author":"Kaur","year":"2022","journal-title":"Head Neck Pathol"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1136\/bjo.2004.047092","article-title":"Plasmacellular differentiation in extranodal marginal zone B cell lymphomas of the ocular adnexa: an analysis of the neoplastic plasma cell phenotype and its prognostic significance in 136 cases","volume":"89","author":"Coupland","year":"2005","journal-title":"Br J Ophthalmol"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2015-12-624304","article-title":"The spectrum of MALT lymphoma at different sites: biological and therapeutic relevance","volume":"127","author":"Zucca","year":"2016","journal-title":"Blood"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1038\/nrgastro.2010.58","article-title":"Gastric MALT lymphoma: a model of chronic inflammation-induced tumor development","volume":"7","author":"Sagaert","year":"2010","journal-title":"Nat Rev Gastroenterol Hepatol"},{"key":"B5","article-title":"Clinicopathologic characteristics and treatment of marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma)","volume":"66","author":"Raderer","year":"2015","journal-title":"CA: A Cancer J Clin"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1182\/bloodadvances.2022007772","article-title":"Predictors of survival in patients with MALT lymphoma: a retrospective, case-control study","volume":"7","author":"Qi","year":"2023","journal-title":"Blood Adv"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000009648","article-title":"Marginal zone lymphoma of palatine tonsil with prominent plasmacytic differentiation","volume":"97","author":"Ma","year":"2018","journal-title":"Medicine"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1182\/blood.2019000931","article-title":"Overview of castleman disease","volume":"135","author":"Fajgenbaum","year":"2020","journal-title":"Blood"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1002\/ajh.25487","article-title":"Mantle cell lymphoma: 2019 update on the diagnosis, pathogenesis, prognostication, and management","volume":"94","author":"Jain","year":"2019","journal-title":"Am J Hematol"},{"key":"B10","doi-asserted-by":"publisher","DOI":"10.1002\/ajh.26523","article-title":"Mantle cell lymphoma in 2022\u2014A comprehensive update on molecular pathogenesis, risk stratification, clinical approach, and current and novel treatments","volume":"97","author":"Jain","year":"2022","journal-title":"Am J Hematol"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.5858\/arpa.2018-0188-RS","article-title":"Pulmonary nodular lymphoid hyperplasia","volume":"143","author":"Yell","year":"2019","journal-title":"Arch Pathol Lab Med"}],"container-title":["Frontiers in Oncology"],"original-title":[],"link":[{"URL":"https:\/\/www.frontiersin.org\/articles\/10.3389\/fonc.2026.1718760\/full","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,5]],"date-time":"2026-03-05T05:25:26Z","timestamp":1772688326000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.frontiersin.org\/articles\/10.3389\/fonc.2026.1718760\/full"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,3,5]]},"references-count":11,"alternative-id":["10.3389\/fonc.2026.1718760"],"URL":"https:\/\/doi.org\/10.3389\/fonc.2026.1718760","relation":{},"ISSN":["2234-943X"],"issn-type":[{"value":"2234-943X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,3,5]]},"article-number":"1718760"}}
