[Multifactorial classification of vasculitis. A critical review]

The present classification of vasculitis has several objections, based on the following aspects: 1) It does not take into account taxonomic rules; 2) It uses criteria which helps to cover up; 3) It uses generic terms without a specific meaning; 4) Lack of clinical interest. We comment on the best known classifications focusing on the main objections. We propose a multifactorial classification based on Klemperer, Pollak and Baehr studies.
