Some cases have demonstrated malignant disease. In the head and neck lesion in particular, IgG4-producing mucosa-associated lymphoid tissue (MALT) lymphoma has arisen during the treatment of IgG4-related disease. We herein report the first case of IgG4-producing MALT lymphoma during the treatment of IgG4-related disease in the renal hilum. A 79-year-old man was being followed for autoimmune pancreatitis and IgG4-related sclerosing cholangitis. During follow-up, magnetic resonance cholangiopancreatography detected a mass in the renal hilum, so he was referred to our department for a further examination. Positron emission tomography-computed tomography detected a standard uptake of 9.7, and the tumor size was gradually increasing. Due to these findings, laparoscopic nephro-ureterectomy was performed. A pathological examination revealed IgG4-producing marginal zone B cell lymphoma. We herein report a rare case of IgG4-producing B cell lymphoma in the renal hilum.<\/jats:p>","DOI":"10.1159\/000504699","type":"journal-article","created":{"date-parts":[[2019,11,27]],"date-time":"2019-11-27T22:01:17Z","timestamp":1574892077000},"page":"880-884","source":"Crossref","is-referenced-by-count":2,"title":["IgG4-Producing MALT Lymphoma in the Renal Hilum"],"prefix":"10.1159","volume":"12","author":[{"given":"Kota","family":"Shimokihara","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7049-3379","authenticated-orcid":false,"given":"Takashi","family":"Kawahara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryo","family":"Kasahara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Kasuga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinpei","family":"Sugiura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryosuke","family":"Tajiri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroji","family":"Uemura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kimio","family":"Chiba","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2019,11,27]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.3109\/s10165-011-0520-x"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0b013e31816148ad"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1007\/s00795-016-0139-2"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.semarthrit.2017.07.011"}],"container-title":["Case Reports in Oncology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/504699","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/504699","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T16:14:00Z","timestamp":1745424840000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000504699"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,11,27]]},"references-count":4,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2020,1,2]]}},"URL":"https:\/\/doi.org\/10.1159\/000504699","archive":["Portico"],"relation":{},"ISSN":["1662-6575"],"issn-type":[{"value":"1662-6575","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,11,27]]}}}
