Multi-center observational study to evaluate the histopathology and transcriptome of cutaneous lesions in patients with several different types of vasculitis.


This study employs a multi-center approach to evaluate cutaneous vasculitis across several forms of idiopathic vasculitis. Patients with cutaneous manifestations of vasculitis will be evaluated by teams of primary vasculitis care providers and Dermatologists in order to facilitate optimal selection of patients and sampling of lesions.

A punch skin biopsy at a site of active vasculitis will be the source of material for histopathologic and transcriptomic evaluation. The histopathology of cutaneous vasculitis will be characterized using a standardized approach.

You have an uncontrolled disease that could prevent you from completing the study procedures
You have an active infection at or near the potential biopsy site, have poor circulation, or have bony prominence or other structure that would increase your risk of complications if you participated in this study
