We report a case of a 63\u2010year\u2010old woman with an unresectable base\u2010of\u2010tongue tumor initially presumed to be squamous cell carcinoma. Histopathologic evaluation and molecular testing ultimately confirmed HCCC with an EWSR1\u2010ATF1 fusion. Given the tumor\u2019s extent, she was treated with definitive chemoradiation using weekly cisplatin and 70\u2009Gy in 35 fractions. Her course was complicated by pulmonary embolism, neutropenia, and severe mucositis requiring percutaneous endoscopic gastrostomy tube placement. Post\u2010treatment imaging showed decreased FDG avidity, and circulating tumor DNA remained negative for minimal residual disease. This case highlights the importance of molecular diagnostics in distinguishing HCCC from other clear cell neoplasms and suggests a potential role for chemoradiation in unresectable cases, though treatment\u2010related toxicity remains a significant concern. Further investigation into systemic and targeted therapies for HCCC is warranted.<\/jats:p>","DOI":"10.1155\/crom\/6717205","type":"journal-article","created":{"date-parts":[[2025,12,15]],"date-time":"2025-12-15T16:38:47Z","timestamp":1765816727000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Definitive Chemoradiation for Unresectable Hyalinizing Clear Cell Carcinoma of the Base of the Tongue: A Molecularly Confirmed Case"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-3878-6240","authenticated-orcid":false,"given":"Paul J.","family":"Pecorin","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-3021-7627","authenticated-orcid":false,"given":"Mary","family":"Allen-Proctor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4160-7496","authenticated-orcid":false,"given":"Samer","family":"Al-Khudari","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2808-722X","authenticated-orcid":false,"given":"Daniel W.","family":"Golden","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7459-1761","authenticated-orcid":false,"given":"Koosha","family":"Paydary","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,12,15]]},"reference":[{"key":"e_1_2_10_1_2","volume-title":"StatPearls","author":"Young A.","year":"2023"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/hed.23902"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/0194599819835779"},{"key":"e_1_2_10_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.oooo.2012.02.003"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.3389\/fonc.2024.1384913"},{"key":"e_1_2_10_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/hed.24637"},{"key":"e_1_2_10_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tripleo.2011.02.041"},{"key":"e_1_2_10_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.23974"},{"key":"e_1_2_10_9_2","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0b013e31825485c5"},{"key":"e_1_2_10_10_2","doi-asserted-by":"publisher","DOI":"10.1158\/2767-9764.CRC-22-0518"},{"key":"e_1_2_10_11_2","doi-asserted-by":"publisher","DOI":"10.3389\/fphar.2020.621093"}],"container-title":["Case Reports in Oncological Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crom\/6717205","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1155\/crom\/6717205","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crom\/6717205","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,17]],"date-time":"2026-03-17T19:02:44Z","timestamp":1773774164000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/crom\/6717205"}},"subtitle":[],"editor":[{"given":"Jose I.","family":"Mayordomo","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]}],"short-title":[],"issued":{"date-parts":[[2025,1]]},"references-count":11,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2025,1]]}},"alternative-id":["10.1155\/crom\/6717205"],"URL":"https:\/\/doi.org\/10.1155\/crom\/6717205","archive":["Portico"],"relation":{},"ISSN":["2090-6706","2090-6714"],"issn-type":[{"value":"2090-6706","type":"print"},{"value":"2090-6714","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,1]]},"assertion":[{"value":"2025-07-01","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-11-17","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-12-15","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"6717205"}}
