Actinomycoses in the nasopharynx are extremely rare, especially in the Rosenm\u00fcller\u2019s fossa. This report presents a case of actinomycosis in the Rosenm\u00fcller\u2019s fossa. A 75-year-old woman presented with a 6-month history of bloody sputum. A grayish-white caseous tissue was found in the right Rosenm\u00fcller\u2019s fossa after retracting the torus tubarius. Magnetic resonance imaging showed a well-defined lesion with low-signal intensity on T1- and T2-weighted images; small low-signal areas were interspersed inside. The lesion was removed under an endoscope. Histopathological examination revealed eosinophilic, club-shaped structures surrounding a hematoxylophilic center, leading to the diagnosis of actinomycosis. The symptoms improved after 3 months of amoxicillin administration but recurred quickly. After 6 months of amoxicillin administration, the bloody sputum disappeared, and local and imaging findings were normal.<\/jats:p>","DOI":"10.1177\/0145561320974850","type":"journal-article","created":{"date-parts":[[2020,11,25]],"date-time":"2020-11-25T08:24:30Z","timestamp":1606292670000},"page":"NP389-NP391","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["A Case of Actinomycosis in the Rosenm\u00fcller\u2019s Fossa"],"prefix":"10.1177","volume":"101","author":[{"given":"Takahiro","family":"Kusaka","sequence":"first","affiliation":[{"name":"Department of Otolaryngology, Head and Neck Surgery, Iwate Medical University, Shiwa, Iwate, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3660-192X","authenticated-orcid":false,"given":"Shigeru","family":"Kuwashima","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Head and Neck Surgery, Iwate Medical University, Shiwa, Iwate, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harukazu","family":"Hiraumi","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Head and Neck Surgery, Iwate Medical University, Shiwa, Iwate, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroaki","family":"Sato","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Head and Neck Surgery, Iwate Medical University, Shiwa, Iwate, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,11,25]]},"reference":[{"key":"bibr1-0145561320974850","first-page":"183","volume":"7","author":"Valour F","year":"2014","journal-title":"Infect Drug Resist"},{"key":"bibr2-0145561320974850","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000010406"},{"key":"bibr3-0145561320974850","doi-asserted-by":"publisher","DOI":"10.3892\/ol.2015.3157"},{"key":"bibr4-0145561320974850","doi-asserted-by":"publisher","DOI":"10.1007\/s00062-011-0119-9"},{"key":"bibr5-0145561320974850","first-page":"367364","volume":"2011","author":"Ouertatani L","year":"2011","journal-title":"Case Rep Otolaryngol"},{"key":"bibr6-0145561320974850","doi-asserted-by":"publisher","DOI":"10.1016\/j.anl.2006.05.015"},{"key":"bibr7-0145561320974850","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200408000-00016"},{"key":"bibr8-0145561320974850","doi-asserted-by":"publisher","DOI":"10.1177\/000348940010900614"},{"key":"bibr9-0145561320974850","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215100136734"},{"key":"bibr10-0145561320974850","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215100105961"},{"issue":"5","key":"bibr11-0145561320974850","first-page":"317","volume":"111","author":"Kitamura M","year":"2018","journal-title":"Pract Otorhinolaryngol (Basel)"},{"issue":"3","key":"bibr12-0145561320974850","first-page":"331","volume":"24","author":"Park JK","year":"2003","journal-title":"AJNR Am J Neuroradiol"},{"key":"bibr13-0145561320974850","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejrad.2009.05.021"},{"key":"bibr14-0145561320974850","doi-asserted-by":"publisher","DOI":"10.1111\/ijd.14833"}],"container-title":["Ear, Nose &amp; Throat Journal"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0145561320974850","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/0145561320974850","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0145561320974850","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T18:34:19Z","timestamp":1777401259000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.1177\/0145561320974850"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,11,25]]},"references-count":14,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2022,11]]}},"alternative-id":["10.1177\/0145561320974850"],"URL":"https:\/\/doi.org\/10.1177\/0145561320974850","relation":{},"ISSN":["0145-5613","1942-7522"],"issn-type":[{"value":"0145-5613","type":"print"},{"value":"1942-7522","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,11,25]]}}}
