Salivary gland tumours in childhood are rare, with an annual incidence of less than 1 per million, representing fewer than 10% of paediatric head and neck cancers. Although the annual incidence of paediatric salivary gland malignancies is less than 1 per million, a salivary gland neoplasm presenting in a child carries a 50\u201360% probability of malignancy, with sialoblastoma accounting for approximately 4% of all salivary gland tumours.<\/jats:p>\n                  <jats:p>We report the case of a term newborn who presented with a firm left infra-auricular swelling at birth. Initial ultrasound imaging revealed a well-defined, round lesion with homogeneous internal echogenicity and acoustic enhancement. Subsequent MRI of the neck demonstrated a well-circumscribed, solitary lesion within the left parotid gland. Histopathological examination revealed features consistent with a primary malignant salivary gland tumour, with morphology and immunophenotype suggestive of sialoblastoma. The newborn was treated with complete surgical excision and remained disease-free at 3\u2009months post surgery.<\/jats:p>","DOI":"10.1136\/bcr-2025-270561","type":"journal-article","created":{"date-parts":[[2026,4,24]],"date-time":"2026-04-24T14:30:25Z","timestamp":1777041025000},"page":"e270561","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Sialoblastoma: a malignant congenital salivary gland tumour"],"prefix":"10.1136","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-2420-218X","authenticated-orcid":false,"given":"Aaya","family":"Seedahmed","sequence":"first","affiliation":[{"name":"Maternity, University Hospitals of North Midlands NHS Trust, Stoke-on-Trent, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adriel","family":"Roa-Bautista","sequence":"additional","affiliation":[{"name":"University Hospitals of North Midlands NHS Trust, Stoke-on-Trent, England, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Asha","family":"Shenvi","sequence":"additional","affiliation":[{"name":"Neonatal Intensive Care Unit, University Hospitals of North Midlands NHS Trust, Stoke-on-Trent, England, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2026,4,24]]},"reference":[{"key":"2026042407302063000_19.4.e270561.1","first-page":"1140","article-title":"Subglottotracheal Adenoid Cystic Carcinoma in a 16-Year-Old Female\u2014A Case Report","volume":"59","author":"Dumitru","year":"2023","journal-title":"Med Bogota Colomb"},{"key":"2026042407302063000_19.4.e270561.2","doi-asserted-by":"crossref","unstructured":"Surun A , Schneider DT , Ferrari A , et al .
