Bronchiolitis obliterans syndrome (BOS) is the most prevalent late noninfectious pulmonary complication in patients who underwent allogeneic haematopoietic stem cell transplantation (HSCT). Therefore, patients experiencing progressive dyspnea and chronic cough after allogenic HSCT, with new obstructive pattern on pulmonary function test, are typically diagnosed with post\u2010transplant BOS. However, it is important to note that TBM can also manifest as an obstructive defect pattern on pulmonary function test. Tracheomalacia has been reported as a rare complication of allogenic stem cell transplantation. We present two patients who developed TBM following allogeneic HSCT and were initially treated for post\u2010transplant BOS but did not experience symptom improvement. However, after treatment with continuous positive airway pressure, their symptom subsided.<\/jats:p>","DOI":"10.1002\/rcr2.1348","type":"journal-article","created":{"date-parts":[[2024,4,30]],"date-time":"2024-04-30T11:29:35Z","timestamp":1714476575000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Tracheobronchomalacia following allogeneic haematopoietic stem cell transplantation"],"prefix":"10.1002","volume":"12","author":[{"given":"Pitirat","family":"Panpruang","sequence":"first","affiliation":[{"name":"Division of Pulmonary and Pulmonary Critical Care Medicine, Department of Medicine, Faculty of Medicine, Ramathibodi Hospital Mahidol University  Bangkok Thailand"},{"name":"Division of Pulmonary and Pulmonary Critical Care Medicine, Department of Medicine, Faculty of Medicine Srinakharinwirot University  Ongkharak Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2383-2398","authenticated-orcid":false,"given":"Dararat","family":"Eksombatchai","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Pulmonary Critical Care Medicine, Department of Medicine, Faculty of Medicine, Ramathibodi Hospital Mahidol University  Bangkok Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2115-3984","authenticated-orcid":false,"given":"Viboon","family":"Boonsarngsuk","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Pulmonary Critical Care Medicine, Department of Medicine, Faculty of Medicine, Ramathibodi Hospital Mahidol University  Bangkok Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,4,30]]},"reference":[{"issue":"4","key":"e_1_2_9_2_1","first-page":"1012","article-title":"Tracheobronchomalacia and excessive dynamic airway collapse: current concepts and future directions","volume":"42","author":"Aslam A","year":"2022","journal-title":"Clin Chest Med"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/bmt.2014.175"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00052806"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2016-08-693507"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bbmt.2014.12.001"},{"key":"e_1_2_9_7_1","first-page":"8:13","article-title":"Clinical advances in the evaluation of patients with excessive central airway collapse: a narrative review","author":"Ramakrishnan K","year":"2022","journal-title":"J Visual Surg"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.4103\/0970-2113.184870"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1378\/chest.127.3.984"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2009.1018"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1183\/23120541.00185-2022"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/0046-8177(95)90174-4"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.4103\/lungindia.lungindia_89_18"}],"container-title":["Respirology Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/rcr2.1348","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,29]],"date-time":"2024-05-29T00:15:19Z","timestamp":1716941719000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/rcr2.1348"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,4,30]]},"references-count":12,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2024,5]]}},"alternative-id":["10.1002\/rcr2.1348"],"URL":"https:\/\/doi.org\/10.1002\/rcr2.1348","archive":["Portico"],"relation":{},"ISSN":["2051-3380","2051-3380"],"issn-type":[{"type":"print","value":"2051-3380"},{"type":"electronic","value":"2051-3380"}],"subject":[],"published":{"date-parts":[[2024,4,30]]},"assertion":[{"value":"2024-02-20","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-04-02","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-04-30","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e01348"}}
