He had previously required ventilatory support and had history of intubation for 1 week. A flexible fibre-optic laryngoscopy showed a smooth mass covering the laryngeal inlet which moved with respiration. Direct laryngoscopy under general anaesthesia revealed a smooth mucosa covered fleshy mass arising from the left aryepiglottic fold and arytenoid, obstructing the laryngeal inlet. The mass was removed using controlled plasma ablation, and histopathological examination of the same was consistent with lymphangioma. Endoscopic examinations during the regular follow-up visits revealed well-healed supraglottic area with adequate glottic chink and the patient could be successfully decannulated.<\/jats:p>","DOI":"10.1136\/bcr-2020-240130","type":"journal-article","created":{"date-parts":[[2021,1,27]],"date-time":"2021-01-27T12:38:51Z","timestamp":1611751131000},"page":"e240130","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Laryngeal lymphangioma as a cause of respiratory distress in an adult with Down\u2019s syndrome: an extremely rare presentation"],"prefix":"10.1136","volume":"14","author":[{"given":"Neha","family":"Chauhan","sequence":"first","affiliation":[{"name":"ENT, Post Graduate Institute of Medical Education and Research, Chandigarh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Balaji","family":"Ramamourthy","sequence":"additional","affiliation":[{"name":"ENT, Post Graduate Institute of Medical Education and Research, Chandigarh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manjul","family":"Muraleedharan","sequence":"additional","affiliation":[{"name":"ENT, Post Graduate Institute of Medical Education and Research, Chandigarh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ramandeep Singh","family":"Virk","sequence":"additional","affiliation":[{"name":"ENT, Post Graduate Institute of Medical Education and Research, Chandigarh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2021,1,27]]},"reference":[{"key":"2025082706501137000_14.1.e240130.1","doi-asserted-by":"crossref","first-page":"899","DOI":"10.1016\/j.ijporl.2014.03.012","article-title":"A general review of the otolaryngologic manifestations of Down syndrome","volume":"78","author":"Chin","year":"2014","journal-title":"Int J Pediatr Otorhinolaryngol"},{"key":"2025082706501137000_14.1.e240130.2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8749.2004.tb00483.x"},{"key":"2025082706501137000_14.1.e240130.3","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.ijporl.2015.11.027","article-title":"International Journal of pediatric otorhinolaryngology the prevalence of airway problems in children with Down \u2019 S syndrome","volume":"81","author":"Hamilton","year":"2016","journal-title":"Int J Pediatr Otorhinolaryngol"},{"key":"2025082706501137000_14.1.e240130.4","doi-asserted-by":"crossref","first-page":"20","DOI":"10.1007\/s12105-010-0230-2","article-title":"Lymphangioma of the vallecula","volume":"5","author":"Castle","year":"2011","journal-title":"Head Neck Pathol"},{"key":"2025082706501137000_14.1.e240130.5","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1960.00740010256018"},{"key":"2025082706501137000_14.1.e240130.6","first-page":"1","article-title":"Lymphangiomas of the larynx in infants and children.
