In this paper, we report a case of primary nasopharyngeal mucosal melanoma. Methods: A case of primary nasopharyngeal mucosal melanoma was reported, and its clinical symptoms, pathological characteristics, treatment and follow-up were described in detail. Results: This report describes a 59-year-old male patient with persistent nasal congestion and suspected malignant nasopharyngeal neoplasm. Patients receive surgical resection and adjuvant radiotherapy after complete resection. Imaging studies showed no tissue invasion or lymph node metastases. The results of immunohistochemistry were Melan-A(+), HMB45(+), and S100(+). The final diagnosis was malignant nasopharyngeal melanoma. After 2 years of follow-up, the prognosis was good, and there was no metastasis or recurrence. Discussion: Nasopharyngeal melanoma is a rare malignancy with a poor prognosis, and surgical resection is the mainstay of treatment. Postoperative adjuvant therapy can improve the rate of local control of lesions. Early diagnosis and thorough examination are extremely important for the patient\u2019s prognosis.<\/jats:p>","DOI":"10.1177\/01455613241237772","type":"journal-article","created":{"date-parts":[[2024,3,5]],"date-time":"2024-03-05T02:30:55Z","timestamp":1709605855000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Primary Nasopharyngeal Melanoma without invasive and Metastasis: A Rare Case Reports and Literature Reviews"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-9289-8535","authenticated-orcid":false,"given":"Jian-Jun","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology, Tangshan Workers Hospital Affiliated to Hebei Medical University, Tangshan City, Hebei Province, China"},{"name":"Hebei Medical University, Shijiazhuang City, Hbeei Province, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yao-Dong","family":"Huan","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, The Affiliated Hospital of North China University of Science and Technology, Tangshan City, Hebei Province, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hua","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Tangshan Workers Hospital Affiliated to Hebei Medical University, Tangshan City, Hebei Province, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,3,4]]},"reference":[{"issue":"7","key":"bibr1-01455613241237772","first-page":"1105","volume":"37","author":"Uehara T","year":"1987","journal-title":"Acta Pathol Jpn"},{"key":"bibr2-01455613241237772","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200305000-00004"},{"key":"bibr3-01455613241237772","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijscr.2015.03.053"},{"issue":"1","key":"bibr4-01455613241237772","first-page":"9","volume":"48","author":"Holmstrom M","year":"1991","journal-title":"Br J Ind Med"},{"key":"bibr5-01455613241237772","doi-asserted-by":"publisher","DOI":"10.1038\/sj.onc.1206460"},{"key":"bibr6-01455613241237772","doi-asserted-by":"publisher","DOI":"10.1002\/hed.23872"},{"key":"bibr7-01455613241237772","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2407-11-85"},{"issue":"1","key":"bibr8-01455613241237772","first-page":"31","volume":"40","author":"Grewal DS","year":"1994","journal-title":"J Postgrad Med"},{"issue":"8","key":"bibr9-01455613241237772","first-page":"739","volume":"5","author":"Mihajlovic M","year":"2012","journal-title":"Int J Clin Exp Pathol"},{"key":"bibr10-01455613241237772","first-page":"8201301","volume":"2017","author":"Alves IS","year":"2017","journal-title":"Case Rep Oncol Med"},{"key":"bibr11-01455613241237772","doi-asserted-by":"publisher","DOI":"10.3390\/ijms23010147"},{"key":"bibr12-01455613241237772","doi-asserted-by":"publisher","DOI":"10.3389\/fimmu.2021.708293"},{"key":"bibr13-01455613241237772","doi-asserted-by":"publisher","DOI":"10.15586\/codon.noncutaneousmelanoma.2018.ch4"},{"key":"bibr14-01455613241237772","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200106000-00010"},{"key":"bibr15-01455613241237772","doi-asserted-by":"publisher","DOI":"10.1007\/s12105-017-0789-y"},{"key":"bibr16-01455613241237772","doi-asserted-by":"publisher","DOI":"10.1002\/hed.20785"},{"key":"bibr17-01455613241237772","doi-asserted-by":"publisher","DOI":"10.1007\/s12105-012-0375-2"},{"key":"bibr18-01455613241237772","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2407-14-608"},{"key":"bibr19-01455613241237772","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijrobp.2014.03.042"},{"key":"bibr20-01455613241237772","doi-asserted-by":"publisher","DOI":"10.1001\/archoto.2010.217"},{"key":"bibr21-01455613241237772","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijrobp.2006.01.016"}],"container-title":["Ear, Nose &amp;
