Livedoid vasculopathy as a marker of systemic disease: report of two cases.

The livedoid vasculopathy is an obstructive vascular process of etiology not yet fully known, being possibly associated with several prothrombotic events. It is clinically characterized by the presence of painful and recurring purpuric lesions, which usually suffer ulceration and evolve with formation of white atrophic scars usually located in the lower limbs. Two cases are here reported of painful ulcerated lesions on the lower limbs, in which the identification of VL enabled the diagnosis of systemic diseases.
