She subsequently underwent endoscopic airway assessment with microlaryngoscopy and bronchoscopy proceeding to open excision of the lesion in the right thyroid lobe on day thirteen of life, resulting in resolution of airway compromise and complete pathological clearance. The baby was discharged 10 days after surgery. Histology confirmed a thyroid teratoma. At 12 months, the child was thriving with no evidence of recurrence. This case illustrates a rare but serious diagnosis that, if not managed in a timely manner, can lead to significant morbidity and mortality.<\/jats:p>","DOI":"10.1136\/bcr-2021-243942","type":"journal-article","created":{"date-parts":[[2022,1,21]],"date-time":"2022-01-21T10:20:49Z","timestamp":1642760449000},"page":"e243942","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Thyroid teratoma in a newborn"],"prefix":"10.1136","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0965-7477","authenticated-orcid":false,"given":"Joseph","family":"Roscamp","sequence":"first","affiliation":[{"name":"Academic Unit of Medical Education, The University of Sheffield, Sheffield, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sabapathy","family":"Balasubramanian","sequence":"additional","affiliation":[{"name":"Endocrine Surgery, Northern General Hospital, South Yorkshire, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9083-8151","authenticated-orcid":false,"given":"Sanjeev L","family":"Gupta","sequence":"additional","affiliation":[{"name":"Ear, Nose and Throat Surgery, Sheffield Children's Hospital NHS Foundation Trust, Sheffield, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2022,1,21]]},"reference":[{"key":"2025082803291428000_15.1.e243942.1","doi-asserted-by":"crossref","first-page":"41","DOI":"10.1016\/S0266-4356(03)00174-8","article-title":"Diagnosis and management of cervical teratomas","volume":"42","author":"Berg\u00e9","year":"2004","journal-title":"Br J Oral Maxillofac Surg"},{"key":"2025082803291428000_15.1.e243942.2","doi-asserted-by":"crossref","first-page":"193","DOI":"10.1007\/s12070-011-0224-8","article-title":"Head and neck teratomas in children: a case series","volume":"63","author":"Chakravarti","year":"2011","journal-title":"Indian J Otolaryngol Head Neck Surg"},{"key":"2025082803291428000_15.1.e243942.3","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-198309000-00016"},{"key":"2025082803291428000_15.1.e243942.4","doi-asserted-by":"crossref","first-page":"236","DOI":"10.1177\/0284185117710680","article-title":"Sacrococcygeal teratomas in newborns: a comprehensive review for the radiologists","volume":"59","author":"Yoon","year":"2018","journal-title":"Acta Radiol"},{"key":"2025082803291428000_15.1.e243942.5","doi-asserted-by":"publisher","DOI":"10.1007\/s00383-006-1724-6"},{"key":"2025082803291428000_15.1.e243942.6","doi-asserted-by":"publisher","DOI":"10.1016\/S0046-8177(85)80214-8"},{"key":"2025082803291428000_15.1.e243942.7","doi-asserted-by":"crossref","first-page":"1149","DOI":"10.1002\/(SICI)1097-0142(20000301)88:5<1149::AID-CNCR27>3.0.CO;2-V","article-title":"A clinicopathologic study of 30 cases","volume":"88","author":"Thompson","year":"2000","journal-title":"Cancer"},{"key":"2025082803291428000_15.1.e243942.8","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3468(88)80373-7"},{"key":"2025082803291428000_15.1.e243942.9","doi-asserted-by":"crossref","first-page":"225","DOI":"10.1023\/A:1010039317050","article-title":"Unusual types of thyroid cancer","volume":"1","author":"Ain","year":"2000","journal-title":"Rev Endocr Metab Disord"},{"key":"2025082803291428000_15.1.e243942.10","doi-asserted-by":"crossref","first-page":"311","DOI":"10.1002\/1097-0142(197807)42:1<311::AID-CNCR2820420147>3.0.CO;2-V","article-title":"Primary malignant teratoma of the thyroid: case report and literature review of cervical teratomas in adults","volume":"42","author":"Kimler","year":"1978","journal-title":"Cancer"},{"key":"2025082803291428000_15.1.e243942.11","unstructured":"Sharma R , Weerakody Y , Deng F , et al .
