On examination, a non-tender, firm, well-defined, oval swelling of size 3\u00d72\u2009cm was palpable in the left submandibular region that was mobile, non-pulsatile and free from the overlying skin and the underlying muscle. Ultrasonography revealed a bilobed heteroechoic lesion in the left submandibular region with internal vascularity and multiple macrocalcification within it. During the procedure for surgically excising the swelling, we found that it was separate from the gland and vascular structures, had a sinus tracking over and around the left submandibular gland extending beyond the angle of mandible up to the root of a decayed left lower second molar tooth.<\/jats:p>","DOI":"10.1136\/bcr-2019-232681","type":"journal-article","created":{"date-parts":[[2020,2,11]],"date-time":"2020-02-11T04:19:22Z","timestamp":1581394762000},"page":"e232681","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Curious case of submandibular swelling"],"prefix":"10.1136","volume":"13","author":[{"given":"Naveen","family":"Sivadas","sequence":"first","affiliation":[{"name":"Department of General Surgery, Amrita Institute of Medical Sciences and Research Centre, Kochi, Kerala, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2773-5950","authenticated-orcid":false,"given":"Riju","family":"Ramachandran","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Amrita Institute of Medical Sciences and Research Centre, Kochi, Kerala, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anoop V","family":"Pillai","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Amrita Institute of Medical Sciences and Research Centre, Kochi, Kerala, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sivasankar","family":"Krishnakumar","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Amrita Institute of Medical Sciences and Research Centre, Kochi, Kerala, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,2,10]]},"reference":[{"key":"2025082707221267000_13.2.e232681.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joms.2006.02.036"},{"key":"2025082707221267000_13.2.e232681.2","doi-asserted-by":"crossref","first-page":"e529","DOI":"10.1097\/SCS.0b013e3182a238f9","article-title":"Submandibular triangle masses","volume":"24","author":"Dalgic","year":"2013","journal-title":"J Craniofac Surg"},{"key":"2025082707221267000_13.2.e232681.3","doi-asserted-by":"publisher","DOI":"10.1016\/S0278-2391(99)90863-7"},{"key":"2025082707221267000_13.2.e232681.4","doi-asserted-by":"crossref","first-page":"238","DOI":"10.1111\/j.1834-7819.1996.tb04866.x","article-title":"Anatomical considerations in the diagnosis and management of acute maxillofacial bacterial infections","volume":"41","author":"Bridgeman","year":"1996","journal-title":"Aust Dent J"},{"key":"2025082707221267000_13.2.e232681.5","first-page":"351","article-title":"Spread of odontogenic infections: a retrospective analysis and review of the literature","volume":"44","author":"Moghimi","year":"2013","journal-title":"Quintessence Int"},{"key":"2025082707221267000_13.2.e232681.6","unstructured":"Fagan J , Morkel J .
