Insights
Muco-cutaneous angiomas, common in newborns, typically resolve spontaneously. However, early treatment is recommended due to potential scarring and organ involvement.
Area of Science:
- Vascular Anomalies
- Neonatal Dermatology
- Pediatric Surgery
Context:
- Muco-cutaneous angiomas are frequent vascular dysplasias in neonates.
- Lesions often appear post-birth and exhibit significant growth potential.
- Superficial, deep, or mixed types all increase in size until 18 months.
Purpose:
- To evaluate the natural history and treatment implications of muco-cutaneous angiomas in neonates.
- To weigh the benefits of spontaneous resolution against risks of scarring and complications.
- To advocate for timely, appropriate treatment based on clinical presentation.
Summary:
- These vascular lesions typically involute by age 3-4 years, leaving atrophic scars.
- While 90% resolve spontaneously, clinicians debate therapeutic abstention.
- Concerns include scar severity and potential involvement of adjacent structures like eyes and bones.
Impact:
- Recommends routine, early, and appropriate treatment for tuberous angiomas.
- Emphasizes balancing treatment risks with lesion characteristics.
- Aims to improve cosmetic outcomes and prevent functional impairment from these neonatal vascular anomalies.
Abstract:
Muco-cutaneous angiomas are the most common vascular dysplasias in neonates born at term or especially prematurely. Rarely visible at birth, they appear during the first month of life, and always have a very great potential for development. Their extent is variable at onset, and their surface and volume, whatever their type, superficial, deep or mixed, both increase up to the age of 18 months and then diminish to be reabsorbed totally at the age of 3 to 4 years, leaving a zone of atrophic scarring with a cosmetic effect in proportion to the size of the lesion. The spontaneous cure of 90 % of these lesions is the argument used by clinicians who recommend therapeutic abstention. The conspicuous character of the scar, more marked in proportion to the size of the lesion, and the later involvement of organs subjacent to the angioma such as the eye, nasal cartilage, and bones, are the reasons which lead us instead to recommend the routine treatment of every tuberous angioma, provided certainly that such treatment is appropriate to the clinical variety ; treatment should be carried out as soon as possible after birth, and should not represent a risk disproportionate to the innocence of the lesion.
