A carcinoma ex-pleomorphic adenoma (CXPA) is a malignant epithelial neoplasm originating from either a primary or recurrent benign PA. The nasopharynx is an extremely uncommon location for this tumor. A 32-year-old male had complaints of nasal blockage. In noncontrast computed tomography, a soft-tissue mass was present in the nasopharynx. Histopathological and immunohistochemical examination of the endoscopically excised mass revealed features of CXPA, noninvasive in nature. Careful histopathological examination is the key to identify this uncommon entity. To the best of our knowledge, &lt;20 cases have been published so far.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/jomfp.jomfp_241_20","type":"journal-article","created":{"date-parts":[[2021,6,28]],"date-time":"2021-06-28T11:21:51Z","timestamp":1624879311000},"page":"S58-S60","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Nasopharyngeal carcinoma ex-pleomorphic adenoma (noninvasive)"],"prefix":"10.4103","volume":"25","author":[{"given":"Sujata","family":"Naik","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prateek","family":"Das","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rashmi","family":"Patnayak","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Santosh Kumar","family":"Swain","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-14-20240906","doi-asserted-by":"crossref","first-page":"5545","DOI":"10.2147\/CMAR.S198942","article-title":"Sinonasal\/nasopharyngeal pleomorphic adenoma and carcinoma ex pleomorphic adenoma: A report of 17 surgical cases combined with a literature review","volume":"11","author":"Li","year":"2019","journal-title":"Cancer Manag Res"},{"key":"R3-14-20240906","first-page":"1083","article-title":"A case of nasopharyngeal carcinoma ex pleomorphic adenoma","volume":"106","author":"Wasano","year":"2013","journal-title":"Pract Otorhinolaryngol"},{"key":"R4-14-20240906","first-page":"1","article-title":"Carcinosarcoma of the parotid gland: A case report and short review of literature","volume":"5","author":"Patnayak","year":"2007","journal-title":"Internet J Oncol"},{"key":"R5-14-20240906","doi-asserted-by":"crossref","first-page":"137","DOI":"10.1177\/000348948309200208","article-title":"Nasopharyngeal masses in adults","volume":"92","author":"Hopping","year":"1983","journal-title":"Ann Otol Rhinol Laryngol"},{"key":"R6-14-20240906","doi-asserted-by":"crossref","first-page":"e5004","DOI":"10.1097\/MD.0000000000005004","article-title":"Pedunculated carcinoma ex pleomorphic adenoma of the nasal cavity: A unique case report","volume":"95","author":"Liao","year":"2016","journal-title":"Medicine (Baltimore"},{"key":"R7-14-20240906","doi-asserted-by":"crossref","first-page":"223","DOI":"10.1016\/j.anl.2018.08.003","article-title":"Sinonasal pleomorphic adenoma: A single institution case series combined with a comprehensive review of literatures","volume":"46","author":"Rha","year":"2019","journal-title":"Auris Nasus Larynx"},{"key":"R8-14-20240906","first-page":"332","article-title":"Rare benign pleomorphic adenoma of the nose: Short study and literature review","volume":"10","author":"Wierzchowska","year":"2015","journal-title":"Wideochir Inne Tech Maloinwazyjne"},{"key":"R9-14-20240906","doi-asserted-by":"crossref","first-page":"S68","DOI":"10.1007\/s12105-013-0454-z","article-title":"Carcinoma ex pleomorphic adenoma, with particular emphasis on early lesions","volume":"7","author":"Di Palma","year":"2013","journal-title":"Head Neck Pathol"},{"key":"R10-14-20240906","doi-asserted-by":"crossref","first-page":"761","DOI":"10.1097\/00000478-200006000-00001","article-title":"Myoepithelial carcinoma of the salivary glands: A clinicopathologic study of 25 patients","volume":"24","author":"Savera","year":"2000","journal-title":"Am J Surg Pathol"}],"container-title":["Journal of Oral and Maxillofacial Pathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/jomfp.JOMFP_241_20","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T15:21:03Z","timestamp":1787844063000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/jomfp.JOMFP_241_20"}},"subtitle":["A report of a rare case"],"short-title":[],"issued":{"date-parts":[[2021,3]]},"references-count":9,"journal-issue":{"issue":"Suppl 1","published-print":{"date-parts":[[2021]]}},"URL":"https:\/\/doi.org\/10.4103\/jomfp.jomfp_241_20","relation":{},"ISSN":["0973-029X"],"issn-type":[{"value":"0973-029X","type":"print"}],"subject":[],"published":{"date-parts":[[2021,3]]}}}
