However, malignant transformation to carcinoma expleomorphic adenoma (CXPA) is an exceedingly rare occurrence. Malignant patterns reported with pleomorphic adenoma include CXPA, metastasizing pleomorphic adenoma, and carcinosarcoma. Firm mass in the parotid gland is the most common presentation of CXPA. Imaging appearances of CXPA are variable, and the proportion of carcinoma and adenoma components determine the appearance of the lesion on gross pathology. Histopathology remains the gold standard investigation for the confirmation of diagnosis. The treatment of CXPA includes ablative surgical procedure followed by reconstructive surgery. This case report describes the imaging appearances of a rare case of CXPA in a 19-year-old male.<\/jats:p>","DOI":"10.4103\/jmau.jmau_129_20","type":"journal-article","created":{"date-parts":[[2022,2,4]],"date-time":"2022-02-04T02:10:07Z","timestamp":1643940607000},"page":"245-247","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["A Rare Case of Carcinoma Ex-pleomorphic Adenoma"],"prefix":"10.4103","volume":"11","author":[{"given":"Ravikanth","family":"Reddy","sequence":"first","affiliation":[{"name":"Department of Radiology, St. John\u2019s Hospital, Idukki, Kerala, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2022,2,4]]},"reference":[{"key":"R1-20240830","doi-asserted-by":"crossref","first-page":"3253","DOI":"10.4314\/ahs.v19i4.50","article-title":"Carcinoma ex pleomorphic adenoma:A case report and review of literature","volume":"19","author":"Khanna","year":"2019","journal-title":"Afr Health Sci"},{"key":"R2-20240830","doi-asserted-by":"crossref","first-page":"705","DOI":"10.1002\/hed.1100","article-title":"Carcinoma ex pleomorphic adenoma:A clinicopathologic review","volume":"23","author":"Olsen","year":"2001","journal-title":"Head Neck"},{"issue":"Suppl 1","key":"R3-20240830","first-page":"S68","article-title":"Carcinoma ex pleomorphic adenoma, with particular emphasis on early lesions","volume":"7","author":"Di","year":"2013","journal-title":"Head Neck Pathol"},{"key":"R4-20240830","doi-asserted-by":"crossref","first-page":"1154","DOI":"10.1080\/00016489.2016.1191671","article-title":"Carcinoma ex pleomorphic adenoma of the parotid gland:A multi-institutional retrospective analysis in the Northern Japan Head and Neck Cancer Society","volume":"136","author":"Suzuki","year":"2016","journal-title":"Acta Otolaryngol"},{"key":"R5-20240830","doi-asserted-by":"crossref","first-page":"1206","DOI":"10.1097\/01.prs.0000181654.68120.0f","article-title":"Carcinoma ex benign pleomorphic adenoma of the parotid gland","volume":"116","author":"Nouraei","year":"2005","journal-title":"Plast Reconstr Surg"}],"container-title":["Journal of Microscopy and Ultrastructure"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/jmau.jmau_129_20","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,19]],"date-time":"2026-08-19T19:09:08Z","timestamp":1787166548000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/jmau.jmau_129_20"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,2,4]]},"references-count":5,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2023]]}},"URL":"https:\/\/doi.org\/10.4103\/jmau.jmau_129_20","relation":{},"ISSN":["2213-879X","2213-8803"],"issn-type":[{"value":"2213-879X","type":"print"},{"value":"2213-8803","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,2,4]]},"assertion":[{"value":"2020-12-06","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2021-11-21","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
