Atrophie blanche with onset in childhood.

Atrophie blanche (livedo vasculitis) is a superficial thrombotic condition characterized by grouped and reticulated erythematous and purpuric macules, painful ulcers, and atrophic scars, and is usually found in middle-aged women. We describe an 8-year-old boy with atrophie blanche. Therapy with antiplatelet medications seemed to alleviate pain and decrease the ulceration.
