Livedoid vasculopathy: a clinical case proposition

Abstract

Livedoid vasculopathy is a chronic occlusive vasculopathy dermatosis, with a pauciinflammatory or noninflammatory characteristic, and is extremely painful. Its ethiology is not entirely known, being associated with pro-thrombotic events. Characterized by erythematous purpuric maculopapular lesions on the legs, especially on the ankles and feet, that ulcerates and heals with white atrophic scars, named atrophie blanche. Histopathology shows occlusion of dermal vases, segmental hyalinization and endothelial proliferation; there is also a discreet perivascular inflammatory infiltrate. We describe a case of livedoid vasculopathy showing the histopathological findings on the biopsy.
