Here, we present a case of a 3-month-old male infant with a painless left sided submandibular mass. The case highlights the diagnostic power of ultrasound in differentiating ectopic thymic tissue from other pediatric neck masses, often rendering more expensive or invasive imaging unnecessary or potentially counterproductive and allowing to avoid unnecessary procedures and possible complications.<\/jats:p>","DOI":"10.1007\/s40477-025-01082-z","type":"journal-article","created":{"date-parts":[[2025,9,19]],"date-time":"2025-09-19T17:40:00Z","timestamp":1758303600000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Atypical cervical ectopic thymus located in the submandibular space: a case report"],"prefix":"10.1007","author":[{"given":"Emma","family":"Liaci","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcello","family":"Napolitano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Camilla","family":"Viglio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gloria","family":"Pelizzo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelangelo","family":"Baldazzi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rocco","family":"Minelli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Paviglianiti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eugenio","family":"Rossi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2025,9,19]]},"reference":[{"key":"1082_CR1","doi-asserted-by":"publisher","first-page":"2062","DOI":"10.1016\/j.jpedsurg.2021.03.003","volume":"56","author":"A Chang","year":"2021","unstructured":"Chang A, Nataraja RM, Pudel E et al (2021) Diagnosis and management of ectopic cervical thymus in children: systematic review of literature.
