A schwannoma arising in the external auditory canal (EAC) is rare, with few cases reported in the literature. These tumours present a unique challenge and should be considered when patients present with persistent ear symptoms in the absence of common otological pathology. We present a case of a man in his late 60s, referred to the otolaryngology team with unilateral conductive hearing loss and a right-sided EAC mass found on otoscopy. CT and MRI of the head and neck revealed a mass occluding the right EAC, originating from a peripheral cutaneous nerve. Management including biopsy, histopathological analysis and surgical excision in its entirety resulted in a good outcome, leaving a symptom-free patient.<\/jats:p>","DOI":"10.1136\/bcr-2023-257007","type":"journal-article","created":{"date-parts":[[2024,11,4]],"date-time":"2024-11-04T08:10:15Z","timestamp":1730707815000},"page":"e257007","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["A cutaneous sensory nerve schwannoma occluding the external auditory canal"],"prefix":"10.1136","volume":"17","author":[{"given":"John Augustus","family":"Bass","sequence":"first","affiliation":[{"name":"ENT Department, UHSussex, Brighton, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tanya","family":"Gupta","sequence":"additional","affiliation":[{"name":"ENT Department, UHSussex, Brighton, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nick","family":"Saunders","sequence":"additional","affiliation":[{"name":"ENT Department, UHSussex, Brighton, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philippe","family":"Bowles","sequence":"additional","affiliation":[{"name":"ENT, Royal Sussex County Hospital, Brighton, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,11,4]]},"reference":[{"key":"2025082800420748000_17.11.e257007.1","doi-asserted-by":"crossref","DOI":"10.1186\/s13256-018-1584-4","article-title":"Schwannoma with chondroid metaplasia of the external auditory canal \u2013 a rare finding in a rare location: a case report","volume":"12","author":"Bennani","year":"2018","journal-title":"J Med Case Rep"},{"key":"2025082800420748000_17.11.e257007.2","doi-asserted-by":"publisher","DOI":"10.1067\/mhn.2001.114797"},{"key":"2025082800420748000_17.11.e257007.3","unstructured":"Jovanovic MB , Djeric D , Poljovka R , et al .
