Major salivary gland involvement is rare (&lt;5%). The submandibular gland is a highly unusual location for this tumour. Recently, the WHO has updated the classification of salivary gland tumours in which the PA subtype has been modified. We report a very uncommon case of a classical variant of PA involving the submandibular gland in a 49-year-old woman managed at our institute and discuss the most recent pathological criteria for diagnosis, management strategy and prognosis of PA.<\/jats:p>","DOI":"10.1136\/bcr-2021-244218","type":"journal-article","created":{"date-parts":[[2021,8,24]],"date-time":"2021-08-24T12:40:12Z","timestamp":1629808812000},"page":"e244218","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Polymorphous adenocarcinoma of the submandibular gland"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2513-6281","authenticated-orcid":false,"given":"Shiv","family":"Rajan","sequence":"first","affiliation":[{"name":"Surgical Oncology, King George's Medical University, Lucknow, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ajay Kumar","family":"Singh","sequence":"additional","affiliation":[{"name":"Pathology, King George's Medical University, Lucknow, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1139-2444","authenticated-orcid":false,"given":"Sumaira","family":"Qayoom","sequence":"additional","affiliation":[{"name":"Pathology, King George's Medical University, Lucknow, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Palavalasa","family":"Niranjan","sequence":"additional","affiliation":[{"name":"Surgical Oncology, King George's Medical University, Lucknow, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9511-6844","authenticated-orcid":false,"given":"Deep","family":"Chakrabarti","sequence":"additional","affiliation":[{"name":"Radiation Oncology, King George's Medical University, Lucknow, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,8,24]]},"reference":[{"key":"2025082707371734000_14.8.e244218.1","unstructured":"Slootweg P .
