We present an additional case and highlight the importance of early recognition.\n                    <jats:bold>Case presentation:<\/jats:bold>\n                    A previously healthy 10-year-old boy presented with a 3-week history of progressive dyspnea on exertion and nocturnal biphasic stridor, initially mislabelled as refractory asthma. Contrast-enhanced CT revealed a left-sided subglottic soft-tissue mass that reduced the airway lumen to 2.7\u00a0mm, while rigid bronchoscopy confirmed an 80% occlusion caused by a 10\u00a0mm submucosal lesion spanning the cricoid and first tracheal ring. After emergent tracheostomy at the referring institution, he underwent lesion resection and simultaneous decannulation. Histopathology demonstrated spindle-cell proliferation within a myxoid inflammatory stroma; immunohistochemistry was\n                    <jats:italic toggle=\"yes\">ALK-1<\/jats:italic>\n                    \u2013positive, confirming IMT. Post-operative bronchoscopy on day seven showed a widely patent airway. Five years later the child remains asymptomatic and oxygen-independent, with no radiological or endoscopic evidence of recurrence.\n                    <jats:bold>Conclusion:<\/jats:bold>\n                    This case reinforces that persistent pediatric stridor mandates prompt endoscopic evaluation and that complete surgical excision remains the gold-standard therapy for airway IMT. Given the tumour\u2019s intermediate malignant potential and a reported 18\u201340% recurrence rate when margins are positive, meticulous long-term surveillance is indispensable, and\n                    <jats:italic toggle=\"yes\">ALK<\/jats:italic>\n                    -directed therapy should be considered when resection is not feasible. Timely diagnosis and radical local therapy can avert prolonged tracheostomy and enrich the scant literature on pediatric subglottic IMT.\n                  <\/jats:p>","DOI":"10.1177\/20363613251407005","type":"journal-article","created":{"date-parts":[[2026,2,19]],"date-time":"2026-02-19T10:02:29Z","timestamp":1771495349000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Subglottic inflammatory myofibroblastic tumor: A rare case report in a pediatric patient"],"prefix":"10.1177","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0017-1446","authenticated-orcid":false,"given":"Shary","family":"Acosta Su\u00e1rez","sequence":"first","affiliation":[{"name":"Hospital Infantil Universitario de San Jos\u00e9"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lina Estefan\u00eda","family":"Bar\u00f3n M\u00e9ndez","sequence":"additional","affiliation":[{"name":"Fundaci\u00f3n Universitaria de Ciencias de la Salud - FUCS"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Diana Patricia","family":"Romero Lara","sequence":"additional","affiliation":[{"name":"Hospital Infantil Universitario de San Jos\u00e9"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,2,19]]},"reference":[{"key":"e_1_3_9_2_2","doi-asserted-by":"publisher","DOI":"10.4103\/lungindia.lungindia_405_17"},{"key":"e_1_3_9_3_2","doi-asserted-by":"publisher","DOI":"10.1001\/archoto.2011.153"},{"issue":"5","key":"e_1_3_9_4_2","first-page":"144","article-title":"Inflammatory myofibroblastic tumor of the trachea: a case report and review of the literature","volume":"4","author":"F\u0131ndik S","year":"2017","unstructured":"F\u0131ndik S.
