Vasculitis
Vasculitis describes generalized inflammation of vessels. Vasculitides carry a broad range of clinical presentations and as a whole can involve almost any organ system.
Pathology
Some vasculitides are due to direct vessel injury from an infectious agent. However a large proportion show evidence of immune complex related vessel wall injury.
Classification
There are many, often overlapping, types of classification:
- Lie classification of vasculitis (1994)
- 2012 revised International Chapel Hill Consensus Conference nomenclature of vasculitides
