Atrophie blanche, also known as Livedoid vasculitis, is a condition in which scarring occurs on the lower leg due to poor circulation. It appears as a star-shaped or polyangular depressed atrophic plaques of ivory-white color. Enlarged capillaries cause red dots within the scar. Surrounding tissue will also experience a change in pigmentation.

Atrophie blanche generally develops in elderly patients, due to the prevalence of poor circulation in the extremities. It can also be associated with other conditions such as diabetes, venous insufficiency, Livedoid vasculitis, or injury resulting from Cryotherapy or Skin Cancer treatment procedures such as curettage or cautery.
