The diagnosis is usually based on histopathology and immunohistochemistry. A 33-year-old woman presented with acute-onset pain and swelling in the right submandibular region. Clinical examination showed an enlarged submandibular gland, and CT showed a calculus in the Wharton\u2019s duct. After treating the acute phase with antibiotics, the patient underwent submandibular gland excision and calculus removal. Histopathology of the specimen showed areas of periductal sclerosis, acinar atrophy and intense lymphoplasmacytic infiltrates with occasional eosinophils. The IgG4 to IgG plasma cell ratio was &gt;40%, suggestive of an IgG4-related disease. The authors have chosen to report this case because of the unusual presentation of IgG4 disease as acute sialadenitis.<\/jats:p>","DOI":"10.1136\/bcr-2019-231189","type":"journal-article","created":{"date-parts":[[2019,8,29]],"date-time":"2019-08-29T07:38:54Z","timestamp":1567064334000},"page":"e231189","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["An unusual presentation of chronic sclerosing sialadenitis of submandibular gland (Kuttner\u2019s tumour)"],"prefix":"10.1136","volume":"12","author":[{"given":"Somu","family":"Lakshmanan","sequence":"first","affiliation":[{"name":"Otorhinolaryngology and Head and Neck Surgery, Sri Ramachandra University Medical College, Chennai, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1321-5698","authenticated-orcid":false,"given":"Vinoth","family":"Manimaran","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology and Head and Neck Surgery, Sri Ramachandra University Medical College, Chennai, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valliammai","family":"Valliappan","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology and Head and Neck Surgery, Sri Ramachandra University Medical College, Chennai, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vasugi","family":"Arumugam","sequence":"additional","affiliation":[{"name":"Pathology, Sri Ramachandra University Medical College, Chennai, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,8,28]]},"reference":[{"key":"2025082803375264000_12.8.e231189.1","doi-asserted-by":"publisher","DOI":"10.1007\/s00535-003-1175-y"},{"key":"2025082803375264000_12.8.e231189.2","doi-asserted-by":"publisher","DOI":"10.1053\/adpa.2003.50004"},{"key":"2025082803375264000_12.8.e231189.3","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1155\/2018\/6936727","article-title":"Salivary gland pathology in IgG4-related disease: a comprehensive review","volume":"2018","author":"Puxeddu","year":"2018","journal-title":"J Immunol Res"},{"key":"2025082803375264000_12.8.e231189.4","doi-asserted-by":"crossref","first-page":"530","DOI":"10.1007\/s12105-016-0729-2","article-title":"K\u00fcttner tumor: IgG4-related disease of the submandibular gland","volume":"10","author":"Putra","year":"2016","journal-title":"Head Neck Pathol"},{"key":"2025082803375264000_12.8.e231189.5","doi-asserted-by":"publisher","DOI":"10.1097\/01.pas.0000164031.59940.fc"},{"key":"2025082803375264000_12.8.e231189.6","doi-asserted-by":"publisher","DOI":"10.1007\/s10165-011-0571-z"},{"key":"2025082803375264000_12.8.e231189.7","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215115000195"},{"key":"2025082803375264000_12.8.e231189.8","doi-asserted-by":"publisher","DOI":"10.1038\/modpathol.2012.72"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2019-231189","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T10:38:00Z","timestamp":1756377480000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2019-231189"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,8]]},"references-count":8,"journal-issue":{"issue":"8","published-online":{"date-parts":[[2019,8,28]]},"published-print":{"date-parts":[[2019,8]]}},"alternative-id":["10.1136\/bcr-2019-231189"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2019-231189","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2019,8]]}}}
