Complications include airway obstruction, feeding problems, bleeding and infection. Treatment options include surgery, sclerotherapy, medication and conservative management. This case report describes a newborn girl with a large cystic neck malformation. No immediate complications occurred, and she was observed and fed via nasogastric tube. After a multidisciplinary review, a conservative approach was chosen, and the malformation regressed completely within two months.<\/jats:p>","DOI":"10.61409\/v11250981","type":"journal-article","created":{"date-parts":[[2026,8,31]],"date-time":"2026-08-31T08:32:06Z","timestamp":1788165126000},"page":"1-4","source":"Crossref","is-referenced-by-count":0,"title":["Large macrocystic lymphatic malformation in a newborn"],"prefix":"10.61409","author":[{"given":"Rolf Wulff","family":"Cramer","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matias","family":"Gam-Jensen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00f8ren D\u00fchrr","family":"Gade","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sofie Sommer","family":"Hedegaard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"40208","published-online":{"date-parts":[[2026,8,31]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","unstructured":"Gaddikeri S, Vattoth S, Gaddikeri RS et al.
