hemangioma
Let an agent explain haemangiomas and their course in general terms, distinguish them from vascular malformations and other marks, relay guidance on when assessment is advised from paediatric and dermatology sources, and route personal cases to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain haemangiomas and their course in general terms, distinguish them from vascular malformations and other marks, relay guidance on when assessment is advised from paediatric and dermatology sources, and route personal cases to clinicians.
A benign tumour made of blood vessels, most often the infantile haemangioma that appears in the first weeks of life as a raised red mark, grows for months and then shrinks over years, usually without treatment; other haemangiomas occur in the liver, skin and elsewhere, and vascular malformations, which are structural anomalies rather than tumours, are a related but distinct group.
What it is for: Not applicable; a benign growth.
It can be explain kinds and typical course; distinguish haemangiomas from malformations; relay guidance on assessment and treatment in general terms; route personal cases to clinicians.
Distinguishing features
Benign vascular tumour
Growth then involution in infants
Distinct from malformations
Usually needs no treatment
What it looks like
A raised, bright red or bluish mark on the skin in infants, or an internal lesion seen on imaging.
Physical character
infantile haemangioma incidence: about 4-5 percent of infants - estimates vary
involution: over several years - most regress by school age
How it is recognised
Benign blood vessel tumour
Infantile form grows then shrinks
Port-wine stains and arteriovenous malformations are malformations, not haemangiomas

What the second pass must settle

- How should classification and guidelines be linked?
- The registry entry has merged aliases for malformations and other tumours; should they be split off?
