On evaluation, he was noted to have bilateral palsies of cranial nerves III, IV and VI as well as a unilateral right true vocal fold paralysis. CT and MRI studies demonstrated a T2-bright left ethmoid mass with no evidence of bony erosion. Direct visualisation demonstrated a polypoid appearing mass of the left sphenoethmoid recess. Operative biopsy was pursued with final pathology demonstrating benign seromucinous hamartoma. Subsequent blood work demonstrated high titres of anti-acetylcholine receptor antibodies consistent with myasthenia gravis. The patient was started on pyridostigmine with improvement in his ocular cranial neuropathies.<\/jats:p>","DOI":"10.1136\/bcr-2020-240460","type":"journal-article","created":{"date-parts":[[2021,3,15]],"date-time":"2021-03-15T11:40:16Z","timestamp":1615808416000},"page":"e240460","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Confounding case of seromucinous hamartoma"],"prefix":"10.1136","volume":"14","author":[{"given":"Neal Rajan","family":"Godse","sequence":"first","affiliation":[{"name":"Otolaryngology, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe Vittorio","family":"Staltari","sequence":"additional","affiliation":[{"name":"Otolaryngology, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katherine","family":"Doeden","sequence":"additional","affiliation":[{"name":"Pathology, Pittsburgh Veterans Affairs Medical Center, Pittsburgh, Pennsylvania, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8068-9220","authenticated-orcid":false,"given":"Grant Shale","family":"Gillman","sequence":"additional","affiliation":[{"name":"Otolaryngology, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2021,3,15]]},"reference":[{"key":"2025082702225995000_14.3.e240460.1","doi-asserted-by":"crossref","first-page":"241","DOI":"10.1007\/s12105-011-0269-8","article-title":"Seromucinous hamartoma of the nasal cavity: a report of two cases and review of the literature","volume":"5","author":"Khan","year":"2011","journal-title":"Head Neck Pathol"},{"key":"2025082702225995000_14.3.e240460.2","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-018-4885-8"},{"key":"2025082702225995000_14.3.e240460.3","doi-asserted-by":"publisher","DOI":"10.1007\/s12105-009-0159-5"},{"key":"2025082702225995000_14.3.e240460.4","doi-asserted-by":"crossref","first-page":"239","DOI":"10.1007\/s12105-018-0914-6","article-title":"Seromucinous hamartoma of the nasal cavity","volume":"13","author":"Tong","year":"2019","journal-title":"Head Neck Pathol"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2020-240460","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T09:23:10Z","timestamp":1756286590000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2020-240460"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,3]]},"references-count":4,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2021,3,15]]},"published-print":{"date-parts":[[2021,3]]}},"alternative-id":["10.1136\/bcr-2020-240460"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2020-240460","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,3]]}}}
