There have been cases reported in the literature of such tumours occurring in the parotid gland. A 52-year-old man presented with a 4-year history of gradually increasing painless swelling in the right submandibular region. The ultrasound scan of the neck showed features suggestive of a submandibular sialadenitis. The right submandibular gland was then surgically excised and sent for histopathological examination. The features showed a unique dual pathology of the submandibular gland, that is, a plasmacytoma and a pleomorphic adenoma. Such a synchronous double pathology involving the submandibular gland has not been reported in the literature. A review of the literature suggests a good prognosis for the extramedullary plasmacytoma, provided multiple myeloma is ruled out. In 18\u2005months of follow-up, the patient has been asymptomatic with a negative myeloma workup.<\/jats:p>","DOI":"10.1136\/bcr-2013-202463","type":"journal-article","created":{"date-parts":[[2014,3,3]],"date-time":"2014-03-03T11:23:13Z","timestamp":1393845793000},"page":"bcr2013202463","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Dual pathology of the submandibular gland: plasmacytoma and pleomorphic adenoma"],"prefix":"10.1136","volume":"2014","author":[{"given":"Shalini","family":"Menon","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kailesh","family":"Pujary","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manna","family":"Valiathan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2014,3,3]]},"reference":[{"key":"2025042702464483000_2014.mar03_1.bcr2013202463.1","doi-asserted-by":"publisher","DOI":"10.1002\/hed.10048"},{"key":"2025042702464483000_2014.mar03_1.bcr2013202463.2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19890315)63:6<1219::AID-CNCR2820630631>3.0.CO;2-Y"},{"key":"2025042702464483000_2014.mar03_1.bcr2013202463.3","doi-asserted-by":"publisher","DOI":"10.1177\/000348949710600308"},{"key":"2025042702464483000_2014.mar03_1.bcr2013202463.4","doi-asserted-by":"publisher","DOI":"10.1016\/j.anl.2006.07.001"},{"key":"2025042702464483000_2014.mar03_1.bcr2013202463.5","first-page":"331","article-title":"Synchronous unilateral parotid neoplasms of different histological types","volume":"25","author":"Stavirianos","year":"1999","journal-title":"Eur J Surg Oncol"},{"key":"2025042702464483000_2014.mar03_1.bcr2013202463.6","first-page":"E90","article-title":"Synchronous unilateral parotid neoplasms.
