Vasculitis is inflammation of a blood vessel. It is as generic of a term as “sprain.” To get more specific, you must know what kind of vasculitis you are talking about.

Attempts to classify the vasculitides (plural of vasulitis) have raised great controversy, mostly because as a group of disorders they are heterogeneous but overlapping. The most common grouping are into primary, where the vasulitis exists as a entity of itself, and secondary, where it is due to or associated with another disease condition. The primary grouping is then subdivided based on the size/location of the vessels involved. The following is the classification of the 1990 American College of Rheumatology
