[Livedo vasculitis: report of a case]

Abstract

Livedo vasculitis is an occlusive thrombotic hyalinizing vessel disease characterized by parietal hyalinization, endothelial proliferation, fibrin deposits and formation of thrombi within the superficial and deep dermal vessels. Diagnosis, essentially clinical, emphasizes the clinical and histopathological features of livedo vasculitis. We conducted an etiological investigation in our case, as required to diagnose idiopathic livedo vasculitis. Several therapies have been suggested with inconstant results and recurrence after withdrawal. In our case, treatment with recombinant tissue plasminogen activator was successful but was unable to prevent recurrence.
