We report a case of a 54-year-old man, ex-smoker, whose presentation mimicked adult onset asthma with cough and wheezing, which did not respond to conventional treatment. He had occasional haemoptysis and weight loss in which CT scan performed for malignancy screening showed a protruding mass in the distal trachea causing endobronchial obstruction. Bronchoscopic intervention was performed to relieve the obstruction that resulted in resolution of asthmatic symptoms. Histological diagnosis confirmed MEC. This case emphasised the importance of a high index of suspicion in an unusual presentation of a common disease and the pivotal role of bronchoscopic intervention in malignant central airway obstruction.<\/jats:p>","DOI":"10.1136\/bcr-2018-226202","type":"journal-article","created":{"date-parts":[[2019,1,18]],"date-time":"2019-01-18T04:15:15Z","timestamp":1547784915000},"page":"e226202","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Resolution of asthmatic symptoms following successful endoscopic resection of tracheal mucoepidermoid carcinoma"],"prefix":"10.1136","volume":"12","author":[{"given":"Abdul","family":"Hanif Khan","sequence":"first","affiliation":[{"name":"Department of Medicine, Universiti Putra Malaysia Fakulti Perubatan dan Sains Kesihatan, Serdang, Selangor, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7526-361X","authenticated-orcid":false,"given":"Mohamed","family":"Faisal","sequence":"additional","affiliation":[{"name":"Department of Respiratory, Universiti Kebangsaan Malaysia Medical Centre, Cheras, Kuala Lumpur, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Razana","family":"Mohd Ali","sequence":"additional","affiliation":[{"name":"Department of Pathology, Universiti Putra Malaysia Fakulti Perubatan dan Sains Kesihatan, Serdang, Selangor, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jamalul Azizi","family":"Abdul Rahaman","sequence":"additional","affiliation":[{"name":"Department of Pulmonology, Hospital Serdang, Kajang, Selangor, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2019,1,17]]},"reference":[{"key":"2025082802012452000_12.1.e226202.1","doi-asserted-by":"publisher","DOI":"10.1016\/0003-4975(89)90380-9"},{"key":"2025082802012452000_12.1.e226202.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.thorsurg.2013.09.008"},{"key":"2025082802012452000_12.1.e226202.3","doi-asserted-by":"publisher","DOI":"10.1016\/S1010-7940(00)00386-9"},{"key":"2025082802012452000_12.1.e226202.4","doi-asserted-by":"crossref","first-page":"275","DOI":"10.1111\/j.1440-1843.2007.01207.x","article-title":"Prognostic factors of tracheobronchial mucoepidermoid carcinoma\u201315 years experience","volume":"13","author":"Chin","year":"2008","journal-title":"Respirology"},{"key":"2025082802012452000_12.1.e226202.5","doi-asserted-by":"crossref","DOI":"10.1097\/MD.0000000000005292","article-title":"Primary mucoepidermoid carcinoma at the carina of trachea presenting with wheezing in an asthmatic child mimicking an attack of asthma: A case report","volume":"95","author":"Lin","year":"2016","journal-title":"Medicine"},{"key":"2025082802012452000_12.1.e226202.6","unstructured":"Moon EJ , Kim BY , Chung JY , et al .
