RESUMOA vasculopatia livedóide é uma dermatose crônica oclusiva dos vasos sanguíneos da derme, de caráter pauci-inflamatório ou não inflamatório, extremamente dolorosa. A etiologia não é totalmente esclarecida; estando associada a eventos pró-trombóticos. Caracterizada pela presença de lesões maculopapulares, eritêmato-purpúricas, nos membros inferiores, especialmente nos tornozelos e pés que ulceram gerando cicatrizes atróficas, denominadas atrofia branca. A histopatologia evidencia oclusão dos vasos da derme, devido à deposição de fibrina intravascular e presença de trombo intraluminal, além de hialinização segmentar e proliferação endotelial, há também, um infiltrado inflamatório perivascular discreto. Descrevemos um caso de vasculopatia livedóide evidenciando os achados histopatológicos encontrados na biópsia. Palavras ABSTRACTLivedoid 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.
