Sebaceoma extending into the external auditory canal is extremely uncommon. We report the case of an 85-year-old woman who presented with an enlarging mass involving the left tragus and extending into the external auditory canal. Histopathological examination demonstrated dermal nests of basaloid cells with sebaceous differentiation, and immunohistochemical analysis showed focal positivity for epithelial membrane antigen and Ber-EP4, leading to a diagnosis of sebaceoma. Complete excision and reconstruction with a full-thickness skin graft were performed. The postoperative course was uneventful, with complete graft survival, preservation of external auditory canal patency, and no evidence of recurrence at 6\u00a0months postoperatively. This case highlights the rarity of sebaceoma involving the external auditory canal and the importance of considering possible associations with Muir\u2013Torre syndrome.<\/jats:p>","DOI":"10.1093\/jscr\/rjag836","type":"journal-article","created":{"date-parts":[[2026,9,4]],"date-time":"2026-09-04T11:12:21Z","timestamp":1788520341000},"source":"Crossref","is-referenced-by-count":0,"title":["Surgical resection and full-thickness skin grafting for sebaceoma extending into the external auditory canal: a case report"],"prefix":"10.1093","volume":"2026","author":[{"given":"Minami","family":"Yoshimura","sequence":"first","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery, Yodogawa Christian Hospital , Osaka, Osaka ,","place":["Japan"]},{"name":"Department of Plastic and Reconstructive Surgery, Kobe University Graduate School of Medicine , Kobe, Hyogo ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Makoto","family":"Omori","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery, Yodogawa Christian Hospital , Osaka, Osaka ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,9,22]]},"reference":[{"key":"2026092204190211200_ref1","doi-asserted-by":"crossref","first-page":"830","DOI":"10.1017\/S0022215112000874","article-title":"Sebaceoma of the auricle","volume":"126","author":"Jacobson","year":"2012","journal-title":"J Laryngol Otol"},{"key":"2026092204190211200_ref2","doi-asserted-by":"crossref","first-page":"603","DOI":"10.3342\/kjorl-hns.2020.00486","article-title":"Sebaceoma of the external auditory canal","volume":"63","author":"Kim","year":"2020","journal-title":"Korean J Otorhinolaryngol-Head Neck Surg"},{"key":"2026092204190211200_ref3","doi-asserted-by":"crossref","first-page":"980","DOI":"10.1016\/S1470-2045(05)70465-4","article-title":"Muir-Torre syndrome","volume":"6","author":"Ponti","year":"2005","journal-title":"Lancet Oncol"},{"key":"2026092204190211200_ref4","doi-asserted-by":"crossref","first-page":"393","DOI":"10.1007\/s10897-012-9552-4","article-title":"Screening for Muir-Torre syndrome using mismatch repair protein immunohistochemistry of sebaceous neoplasms","volume":"22","author":"Roberts","year":"2013","journal-title":"J Genet Couns"},{"key":"2026092204190211200_ref5","doi-asserted-by":"crossref","first-page":"80","DOI":"10.1111\/j.1365-2559.2007.02722.x","article-title":"Characteristic Ber-EP4 and EMA expression in sebaceoma is immunohistochemically distinct from basal cell carcinoma","volume":"51","author":"Fan","year":"2007","journal-title":"Histopathology"}],"container-title":["Journal of Surgical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/jscr\/article-pdf\/2026\/9\/rjag836\/71303042\/rjag836.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/jscr\/article-pdf\/2026\/9\/rjag836\/71303042\/rjag836.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,22]],"date-time":"2026-09-22T08:19:09Z","timestamp":1790065149000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jscr\/article\/doi\/10.1093\/jscr\/rjag836\/8826522"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,8,31]]},"references-count":5,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2026,8,31]]}},"URL":"https:\/\/doi.org\/10.1093\/jscr\/rjag836","relation":{},"ISSN":["2042-8812"],"issn-type":[{"value":"2042-8812","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2026,9]]},"published":{"date-parts":[[2026,8,31]]},"article-number":"rjag836"}}
