The swelling was non-tender and firm on palpation. The swelling began to increase in size after the extraction of her carious wisdom tooth. Histopathological and serological examinations confirmed the diagnosis of IgG4-related disease, manifested as a mass in the mandible. The patient was prescribed oral corticosteroids at a tapering dosage over 8 weeks. After 3\u2009months, there was an improvement in the patient\u2019s mouth opening and a reduction in the size of the swelling. The patient remains in follow-up care. Including IgG4-related disease in the list of potential diagnoses for oral soft tissue masses is crucial, given their positive response to medical treatment, highlighting the significance of an accurate diagnosis to prevent unnecessary surgery, with oral lesions potentially serving as early indicators before multiorgan complications arise.<\/jats:p>","DOI":"10.1136\/bcr-2024-260749","type":"journal-article","created":{"date-parts":[[2024,7,2]],"date-time":"2024-07-02T01:06:31Z","timestamp":1719882391000},"page":"e260749","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Rare mandibular condition presenting as trismus: an exploration of IgG4-related disease"],"prefix":"10.1136","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7225-9359","authenticated-orcid":false,"given":"Jitendra","family":"Chawla","sequence":"first","affiliation":[{"name":"Dentistry, AIIMS Mangalagiri, Mangalagiri, Andhra Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Poongodi","family":"Rajagopal","sequence":"additional","affiliation":[{"name":"Pathology, AIIMS Mangalagiri, Mangalagiri, Andhra Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8519-4603","authenticated-orcid":false,"given":"Navaneeth","family":"Yerragudi","sequence":"additional","affiliation":[{"name":"Dentistry, AIIMS Mangalagiri, Mangalagiri, Andhra Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JS","family":"Anuvindha","sequence":"additional","affiliation":[{"name":"Dentistry, AIIMS Mangalagiri, Mangalagiri, Andhra Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,7,1]]},"reference":[{"key":"2025082803332275000_17.7.e260749.1","doi-asserted-by":"crossref","first-page":"8179","DOI":"10.3390\/ijerph17218179","article-title":"Igg4-related disease of the oral cavity. case series from a large single-center cohort of Italian patients","volume":"17","author":"Rampi","year":"2020","journal-title":"Int J Environ Res Public Health"},{"key":"2025082803332275000_17.7.e260749.2","doi-asserted-by":"publisher","DOI":"10.1080\/14397595.2020.1859710"},{"key":"2025082803332275000_17.7.e260749.3","doi-asserted-by":"crossref","DOI":"10.1136\/bmj.m1067","article-title":"Advances in the diagnosis and management of Igg4 related disease","volume":"369","author":"Lanzillotta","year":"2020","journal-title":"BMJ"},{"key":"2025082803332275000_17.7.e260749.4","doi-asserted-by":"crossref","first-page":"534","DOI":"10.12809\/hkmj154733","article-title":"Immunoglobulin G4\u2013related sclerosing disease involving the mandible","volume":"23","author":"Tong","year":"2017","journal-title":"Hong Kong Med J"},{"key":"2025082803332275000_17.7.e260749.5","doi-asserted-by":"crossref","first-page":"591","DOI":"10.4103\/jomfp.jomfp_398_21","article-title":"Plasma cells in oral lesion: a clue to diagnosis or a diagnostic dilemma","volume":"26","author":"Kaur","year":"2022","journal-title":"J Oral Maxillofac Pathol"},{"key":"2025082803332275000_17.7.e260749.6","doi-asserted-by":"crossref","first-page":"e40","DOI":"10.1016\/j.oooo.2014.01.023","article-title":"Locally destructive mandibular pseudotumor as a manifestation of immunoglobulin G4-related disease","volume":"118","author":"Guti\u00e9rrez Santamar\u00eda","year":"2014","journal-title":"Oral Surg Oral Med Oral Pathol Oral Radiol"},{"key":"2025082803332275000_17.7.e260749.7","doi-asserted-by":"crossref","DOI":"10.1136\/bcr-2023-256043","article-title":"Igg4-related disease presents as a nasopharyngeal mass","volume":"16","author":"Thongpiya","year":"2023","journal-title":"BMJ Case Rep"},{"key":"2025082803332275000_17.7.e260749.8","first-page":"19","article-title":"Diagnosis and treatment of Igg4-related disease","volume":"401","author":"Kamisawa","year":"2017","journal-title":"Curr Top Microbiol Immunol"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2024-260749","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T10:33:27Z","timestamp":1756377207000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2024-260749"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,7]]},"references-count":8,"journal-issue":{"issue":"7","published-online":{"date-parts":[[2024,7,1]]},"published-print":{"date-parts":[[2024,7]]}},"alternative-id":["10.1136\/bcr-2024-260749"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2024-260749","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2024,7]]}}}
