Standard of treatment consists of surgical resection, but radiation therapy may also be appropriate for incomplete and unresectable tumours. A Hispanic woman in her 40s presented with 2 years of progressive throat pain, dyspnea and cough during meals. CT revealed a polypoid tracheal mass 1.6\u00d71.2\u00d71.7 cm and asymmetric submucosal enhancement and thickening with severe luminal narrowing, which was concerning for malignancy. Rigid bronchoscopy revealed greater than 80% occlusion of the trachea, and biopsy confirmed the diagnosis of ACC with tubular and cribriform patterns. The patient underwent tracheal resection with reanastomosis followed by postoperative adjuvant radiotherapy. Over 1 year later, the patient remains symptom-free and without recurrence of ACC.<\/jats:p>","DOI":"10.1136\/bcr-2024-263368","type":"journal-article","created":{"date-parts":[[2025,4,25]],"date-time":"2025-04-25T04:15:18Z","timestamp":1745554518000},"page":"e263368","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Delayed diagnosis of adenoid cystic carcinoma of the trachea"],"prefix":"10.1136","volume":"18","author":[{"given":"Matthew R","family":"Barke","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, The University of Texas at Austin Dell Medical School, Austin, Texas, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Colleen","family":"O\u2019Neill","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, The University of Texas at Austin Dell Medical School, Austin, Texas, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marisabel","family":"Hurtado Castillo","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, The University of Texas at Austin Dell Medical School, Austin, Texas, USA"},{"name":"Department of Hematology and Oncology, The University of Texas at Austin Dell Medical School, Austin, Texas, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Om","family":"Pandey","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, The University of Texas at Austin Dell Medical School, Austin, Texas, USA"},{"name":"Department of Hematology and Oncology, The University of Texas at Austin Dell Medical School, Austin, Texas, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,4,24]]},"reference":[{"key":"2025082710380624000_18.4.e263368.1","doi-asserted-by":"publisher","DOI":"10.1097\/COC.0b013e3181cae8ab"},{"key":"2025082710380624000_18.4.e263368.2","doi-asserted-by":"crossref","first-page":"1416","DOI":"10.1038\/s41379-019-0277-x","article-title":"Detecting MYB and MYBL1 fusion genes in tracheobronchial adenoid cystic carcinoma by targeted RNA-sequencing","volume":"32","author":"Pei","year":"2019","journal-title":"Mod Pathol"},{"key":"2025082710380624000_18.4.e263368.3","doi-asserted-by":"crossref","first-page":"109746","DOI":"10.1016\/j.ejrad.2021.109746","article-title":"CT diagnosis and prognosis prediction of tracheal adenoid cystic carcinoma","volume":"140","author":"Wang","year":"2021","journal-title":"Eur J Radiol"},{"key":"2025082710380624000_18.4.e263368.4","doi-asserted-by":"crossref","DOI":"10.1186\/s13014-019-1323-z","article-title":"Primary adenoid cystic carcinoma of the trachea: clinical outcome of 38 patients after interdisciplinary treatment in a single institution","volume":"14","author":"H\u00f6gerle","year":"2019","journal-title":"Radiat Oncol"},{"key":"2025082710380624000_18.4.e263368.5","doi-asserted-by":"publisher","DOI":"10.1016\/j.otohns.2004.05.018"},{"key":"2025082710380624000_18.4.e263368.6","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2004.05.064"},{"key":"2025082710380624000_18.4.e263368.7","doi-asserted-by":"crossref","first-page":"3035","DOI":"10.3892\/ol.2017.6511","article-title":"Lung cancer requires multidisciplinary treatment to improve patient survival: A case report","volume":"14","author":"Pezzuto","year":"2017","journal-title":"Oncol Lett"},{"key":"2025082710380624000_18.4.e263368.8","doi-asserted-by":"crossref","DOI":"10.1002\/rcr2.1148","article-title":"Adenoid cystic carcinoma of the trachea mimicking asthma","volume":"11","author":"Wickramasinghe","year":"2023","journal-title":"Respirol Case Rep"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2024-263368","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T17:38:12Z","timestamp":1756316292000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2024-263368"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,4]]},"references-count":8,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2025,4,24]]},"published-print":{"date-parts":[[2025,4]]}},"alternative-id":["10.1136\/bcr-2024-263368"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2024-263368","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2025,4]]}}}
