We present a primary marginal zone B-cell lymphoma of the mucosaassociated lymphoid tissue (MALT) in an 84-year-old female with preexisting metastatic bladder cancer. A PET scan that identified positive pelvic\/cervical lymphadenopathy and bilateral parotid masses. She underwent transurethral resection of a bladder tumor and started on pembrolizumab chemotherapy. After two years, the left parotid mass decreased in size but the right increased to 3.9cm. Right superficial parotidectomy diagnosed B-Cell Marginal zone lymphoma, staining positive for CD20, PAX5, and Bcl2. pembrolizumab was held and the patient was started on 4 weekly rituximab infusions. A PET scan done 3 months after completion of rituximab showed a good response to chemotherapy. This is the first reported case of a primary parotid gland lymphoma in a patient with active metastatic bladder cancer.<\/jats:p>","DOI":"10.1177\/00031348211054526","type":"journal-article","created":{"date-parts":[[2021,11,8]],"date-time":"2021-11-08T06:49:43Z","timestamp":1636354183000},"page":"799-801","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Primary Parotid Non-Hodgkin\u2019s B-Cell Lymphoma in an Elderly Woman on Pembrolizumab for Metastatic Invasive Papillary Urothelial Cell Carcinoma of the Bladder"],"prefix":"10.1177","volume":"88","author":[{"given":"Bismarck","family":"Osumo","sequence":"first","affiliation":[{"name":"Departments of Surgery, Inspira Health Network, Vineland, NJ, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joseph","family":"Radzevich","sequence":"additional","affiliation":[{"name":"Departments of Surgery, Inspira Health Network, Vineland, NJ, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nadia","family":"Nashed","sequence":"additional","affiliation":[{"name":"Departments of Pathology, Inspira Health Network, Vineland, NJ, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Omar","family":"Ustwani","sequence":"additional","affiliation":[{"name":"Departments of Medicine, Inspira Health Network, Vineland, NJ, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gus","family":"Slotman","sequence":"additional","affiliation":[{"name":"Departments of Surgery, Inspira Health Network, Vineland, NJ, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,11,8]]},"reference":[{"key":"bibr1-00031348211054526","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMcpc1800321"},{"issue":"8","key":"bibr2-00031348211054526","first-page":"2050","volume":"13","author":"Wang J","year":"2020","journal-title":"Int J Clin Exp Pathol"},{"key":"bibr3-00031348211054526","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000017042"},{"issue":"4","key":"bibr4-00031348211054526","first-page":"5","volume":"7","author":"Teh AKA","year":"2018","journal-title":"J Am Osteopath Coll Radiol"}],"container-title":["The American Surgeon\u2122"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/00031348211054526","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/00031348211054526","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/00031348211054526","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T12:34:54Z","timestamp":1777379694000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/00031348211054526"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,11,8]]},"references-count":4,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2022,4]]}},"alternative-id":["10.1177\/00031348211054526"],"URL":"https:\/\/doi.org\/10.1177\/00031348211054526","relation":{},"ISSN":["0003-1348","1555-9823"],"issn-type":[{"value":"0003-1348","type":"print"},{"value":"1555-9823","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,11,8]]}}}
