Abstract
Livedoid vasculopathy is a bilateral painful and recurrent cutaneous ulcerative disorder of the legs that leads to atrophie blanche, atrophic white-porcelain scars, and is associated with disorders of fibrinolysis and/or coagulation. We present a young boy with an association between livedoid vasculopathy in the area of a previous involuted cutaneous hemangioma. We found 4 uncommon abnormalities associated with thrombo-occlusive events: heterozygous 20210 A→G genotype of prothrombin, reduced activity of anticoagulation proteins C and S, and elevated lipoprotein (a).
