vasculitis
Let an agent explain vasculitis and its classification, relay causes, symptoms, diagnosis and general treatment from rheumatology sources, describe the forms the registry aliases name, and distinguish vasculitis from atherosclerosis, thrombosis and vasculopathy, routing people 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 vasculitis and its classification, relay causes, symptoms, diagnosis and general treatment from rheumatology sources, describe the forms the registry aliases name, and distinguish vasculitis from atherosclerosis, thrombosis and vasculopathy, routing people to clinicians.
Inflammation of blood vessel walls, which can narrow, block or weaken vessels and damage organs, classified by vessel size in the Chapel Hill nomenclature into large, medium and small vessel vasculitis, including ANCA-associated vasculitis such as granulomatosis with polyangiitis, central nervous system vasculitis, livedoid vasculitis of the skin and autoimmune vasculitides, with microvasculitis affecting the smallest vessels and the Shwartzman phenomenon, an experimental and clinical reaction causing vascular injury. Treatment typically involves immunosuppression under specialist care. The model routes people to clinicians.
What it is for: Not applicable; a group of diseases.
It can be explain classification; relay diagnosis and treatment; route to clinicians; distinguish related conditions.
Distinguishing features
Vessel wall inflammation
Classified by vessel size
Primary or secondary
Immunosuppressive treatment
What it looks like
Not a visible object; sometimes skin rashes or purpura.
Physical character

How it is recognised
Inflammation of blood vessel walls
ANCA-associated, CNS, livedoid, autoimmune vasculitis, microvasculitis, Shwartzman phenomenon
Atherosclerosis is plaque; thrombosis is clotting; vasculopathy is broader vessel disease

- How should rheumatology sources be linked?
- The registry entry has merged aliases naming distinct diseases and the Shwartzman phenomenon; should they be split off?
