Brief Summary

Livedo vasculitis is disease with recurrent courses of painful foot or ankle ulcerations, followed by healed white scars. The actual mechanism of its pathophysiology is not yet clear. It has been reported to be associated with some gene mutations, for example, factor V Leiden gene. This study is aimed to find the possible relation of these gene mutations in Taiwanese patients.
