Blood tests, including platelet count and coagulation parameters, were normal. Doppler ultrasound supported the diagnosis. Follow-up examinations at 1\u2009week, 1\u2009month and 2 months revealed progressive involution of the lesion, characterised by a growing peripheral pale halo, without ulceration or complications. Conservative management was adopted, and no interventions were required. This case highlights the natural regression of rapidly involuting congenital haemangiomas and underscores the importance of clinical observation, parental reassurance and multidisciplinary care in managing such cases.<\/jats:p>","DOI":"10.1136\/bcr-2025-264867","type":"journal-article","created":{"date-parts":[[2026,7,9]],"date-time":"2026-07-09T10:35:14Z","timestamp":1783593314000},"page":"e264867","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["A rapidly involuting congenital haemangioma of the lower limb"],"prefix":"10.1136","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-0062-8772","authenticated-orcid":false,"given":"Filipa Miranda","family":"Santos","sequence":"first","affiliation":[{"name":"Pediatria, Hospital de S\u00e3o Francisco Xavier, Lisboa, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9017-9558","authenticated-orcid":false,"given":"Joana Maria Gomes","family":"Moscoso","sequence":"additional","affiliation":[{"name":"Pediatria, Hospital de S\u00e3o Francisco Xavier, Lisboa, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristina","family":"Amaro","sequence":"additional","affiliation":[{"name":"Centro Hospitalar de Lisboa Ocidental EPE Hospital de Egas Moniz, Lisboa, Lisboa, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2026,7,9]]},"reference":[{"key":"2026070903350661000_19.7.e264867.1","doi-asserted-by":"crossref","first-page":"266","DOI":"10.4103\/2229-5178.160259","article-title":"A tufted angioma","volume":"6","author":"Prasuna","year":"2015","journal-title":"Indian Dermatol Online J"},{"key":"2026070903350661000_19.7.e264867.2","doi-asserted-by":"crossref","DOI":"10.1136\/bcr-2021-247689","article-title":"Rapidly involuting congenital haemangioma: diagnostic and therapeutic approach regarding two case reports","volume":"15","author":"Forjaco Jorge","year":"2022","journal-title":"BMJ Case Rep"},{"key":"2026070903350661000_19.7.e264867.3","doi-asserted-by":"crossref","first-page":"103","DOI":"10.1055\/s-0043-1774391","article-title":"Pediatric Vascular Anomalies: A Clinical and Radiological Perspective","volume":"34","author":"Gupta","year":"2024","journal-title":"Indian J Radiol Imaging"},{"key":"2026070903350661000_19.7.e264867.4","doi-asserted-by":"crossref","first-page":"310","DOI":"10.1093\/pch\/pxac057","article-title":"Vascular anomalies in childhood: When to treat and when to refer","volume":"27","author":"Zwicker","year":"2022","journal-title":"Paediatr Child Health"},{"key":"2026070903350661000_19.7.e264867.5","doi-asserted-by":"crossref","DOI":"10.1136\/bmjpo-2020-000816","article-title":"Congenital haemangiomas: a single-centre retrospective review","volume":"4","author":"Braun","year":"2020","journal-title":"BMJ Paediatr Open"},{"key":"2026070903350661000_19.7.e264867.6","doi-asserted-by":"crossref","DOI":"10.3390\/ijms23042358","article-title":"ISSVA Classification of Vascular Anomalies and Molecular Biology","volume":"23","author":"Kunimoto","year":"2022","journal-title":"Int J Mol Sci"},{"key":"2026070903350661000_19.7.e264867.7","doi-asserted-by":"crossref","first-page":"2274803","DOI":"10.1080\/14767058.2023.2274803","article-title":"Late third trimester diagnosis of congenital giant hemangioma complicated by the Kasabach-Merritt phenomen: a case report and literature review","volume":"36","author":"Fantasia","year":"2023","journal-title":"J Matern Fetal Neonatal Med"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2025-264867","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,9]],"date-time":"2026-07-09T10:35:16Z","timestamp":1783593316000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2025-264867"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7]]},"references-count":7,"journal-issue":{"issue":"7","published-online":{"date-parts":[[2026,7,9]]},"published-print":{"date-parts":[[2026,7]]}},"alternative-id":["10.1136\/bcr-2025-264867"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2025-264867","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,7]]}}}
