Colonoscopy demonstrated a 3\u00d73 cm submucosal rectal mass. Pathological analysis revealed ulcerated colonic mucosa with diffuse proliferation suggestive of a lymphoproliferative process. Immunohistochemistry and flow cytometry of the specimen supported a diagnosis of mucosa-associated lymphoid tissue lymphoma. The patient was treated with amoxicillin, clarithromycin and lansoprazole for 2 weeks. A C-14 urea breath test confirmed eradication of <jats:italic>Helicobacter pylori<\/jats:italic>. Repeat colonoscopy showed no regression of the tumour. The patient received external beam radiation treatment. Subsequent positron emission tomography\/CT scans demonstrated no evidence of viable tumour tissue and no regional or distant metastasis. Follow-up sigmoidoscopy with biopsy revealed no evidence of lymphoma.<\/jats:p>","DOI":"10.1136\/bcr.05.2010.2969","type":"journal-article","created":{"date-parts":[[2011,1,27]],"date-time":"2011-01-27T11:39:05Z","timestamp":1296128345000},"page":"bcr0520102969","source":"Crossref","is-referenced-by-count":11,"title":["Novel approach to treatment of rectal mucosa-associated lymphoid tissue lymphoma"],"prefix":"10.1136","volume":"2011","author":[{"given":"Neetu","family":"Chahil","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Bloom","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeremiah","family":"Tyson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saad","family":"Jazwari","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James","family":"Robilotti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicholas","family":"Gaultieri","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2011,1,27]]},"reference":[{"key":"2025082623050001000_2011.jan27_1.bcr0520102969.1","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19831015)52:8<1410::AID-CNCR2820520813>3.0.CO;2-3"},{"key":"2025082623050001000_2011.jan27_1.bcr0520102969.2","doi-asserted-by":"crossref","first-page":"1378","DOI":"10.1097\/01.smj.0000215855.98512.9d","article-title":"Primary mucosa-associated lymphoid tissue (MALT) lymphoma occurring in the rectum: a case report and review of the literature","volume":"99","author":"Ahlawat","year":"2006","journal-title":"South Med J"},{"key":"2025082623050001000_2011.jan27_1.bcr0520102969.3","doi-asserted-by":"publisher","DOI":"10.1136\/gut.46.1.133"},{"key":"2025082623050001000_2011.jan27_1.bcr0520102969.4","doi-asserted-by":"publisher","DOI":"10.1080\/00365520701858488"},{"key":"2025082623050001000_2011.jan27_1.bcr0520102969.5","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(05)61818-1"},{"key":"2025082623050001000_2011.jan27_1.bcr0520102969.6","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2005.02.9025"},{"key":"2025082623050001000_2011.jan27_1.bcr0520102969.7","doi-asserted-by":"publisher","DOI":"10.1007\/s10350-008-9379-0"},{"key":"2025082623050001000_2011.jan27_1.bcr0520102969.8","doi-asserted-by":"publisher","DOI":"10.1016\/S0016-5107(03)70039-X"},{"key":"2025082623050001000_2011.jan27_1.bcr0520102969.9","doi-asserted-by":"publisher","DOI":"10.3346\/jkms.2005.20.2.325"},{"key":"2025082623050001000_2011.jan27_1.bcr0520102969.10","doi-asserted-by":"publisher","DOI":"10.1055\/s-2002-23643"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr.05.2010.2969","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T06:05:07Z","timestamp":1756274707000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr.05.2010.2969"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011]]},"references-count":10,"alternative-id":["10.1136\/bcr.05.2010.2969"],"URL":"https:\/\/doi.org\/10.1136\/bcr.05.2010.2969","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2011]]}}}
