However, these manifestations are often misdiagnosed as common inflammatory diseases. We report two cases of EGPA diagnosed based on distinct rhinologic presentations. The first case involved a 52-year-old woman who developed mononeuritis multiplex and cutaneous vasculitis following surgery for nasal polyps, which ultimately led to a definitive diagnosis of EGPA. The second case involved a 39-year-old woman who presented with nasal septal perforation and was subsequently diagnosed with an acute exacerbation of EGPA accompanied by pulmonary infiltrates. These cases highlight that not only nasal polyps but also atypical findings, such as nasal septal perforation, may serve as critical diagnostic clues for EGPA. Otorhinolaryngologists play a pivotal role in identifying this potentially fatal systemic vasculitis through careful evaluation of localized sinonasal manifestations.<\/jats:p>","DOI":"10.18787\/jr.2026.00009","type":"journal-article","created":{"date-parts":[[2026,7,29]],"date-time":"2026-07-29T00:16:08Z","timestamp":1785284168000},"page":"120-125","update-policy":"https:\/\/doi.org\/10.18787\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Two Cases of Eosinophilic Granulomatosis With Polyangiitis Presenting With Rhinologic Manifestations"],"prefix":"10.18787","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-5052-9209","authenticated-orcid":true,"given":"Sae Hwan","family":"Park","sequence":"first","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, Dong-A University College of Medicine, Busan, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2180-2905","authenticated-orcid":true,"given":"Chan Ho","family":"Yoon","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, Dong-A University College of Medicine, Busan, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2992-324X","authenticated-orcid":true,"given":"Dong Won","family":"Jung","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, Dong-A University College of Medicine, Busan, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5578-0225","authenticated-orcid":true,"given":"Woo Yong","family":"Bae","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, Dong-A University College of Medicine, Busan, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7989","reference":[{"key":"ref1","first-page":"277","type":"journal-article","volume-title":"Allergic granulomatosis, allergic angiitis, and periarteritis nodosa","author":"Churg","year":"1951"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1097\/mlg.0b013e318159889d","type":"journal-article"},{"key":"ref3","first-page":"870","type":"journal-article","volume-title":"","author":"Jang","year":"2014"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1002\/art.41982","type":"journal-article"},{"key":"ref5","first-page":"65","type":"journal-article","volume-title":"Systemic vasculitis with asthma and eosinophilia: a clinical approach to the Churg-Strauss syndrome","author":"Lanham","year":"1984"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1002\/art.1780330806","type":"journal-article"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1038\/s41584-023-00958-w","type":"journal-article"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.18787\/jr.2025.00036","type":"journal-article"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1097\/00005792-199601000-00003","type":"journal-article"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1002\/art.37721","type":"journal-article"}],"container-title":["Journal of Rhinology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/j-rhinology.org\/upload\/pdf\/jr-2026-00009.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/j-rhinology.org\/journal\/view.php?doi=10.18787\/jr.2026.00009","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/j-rhinology.org\/upload\/pdf\/jr-2026-00009.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,3]],"date-time":"2026-08-03T05:53:51Z","timestamp":1785736431000},"score":1,"resource":{"primary":{"URL":"http:\/\/j-rhinology.org\/journal\/view.php?doi=10.18787\/jr.2026.00009"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,31]]},"references-count":10,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2026,7]]}},"URL":"https:\/\/doi.org\/10.18787\/jr.2026.00009","relation":{},"ISSN":["1229-1498","2384-4361"],"issn-type":[{"value":"1229-1498","type":"print"},{"value":"2384-4361","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,7,31]]},"assertion":[{"value":"2026-02-23","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-05-13","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-07-31","order":2,"name":"published","label":"Published online","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-07-31","order":3,"name":"published","label":"Print publication","group":{"name":"publication_history","label":"Publication History"}}]}}
