a·tro·phie blanche(a-trō'fē blahnsh'),
Small smooth ivory-white areas on the skin with hyperpigmented borders and telangiectasis, developing into atrophic stellate scars; seen especially on the legs and ankles of middle-aged women, and associated with livedo reticularis and dermal hyalinizing vasculitis.
livedoid vasculopathyA thrombogenic vasculopathy caused by fibrin thrombi in the small dermal vessels of the lower legs, especially in older women, which are attributed to decreased fibrinolytic activity in the blood coupled with defective release of intrinsic tissue plasminogen activator from vessel walls. The typical lesions are telangiectatic purpuric papules and plaques which evolve into crusted ulcers that heal into atrophic stellate scars.
Patients may also have livedo reticularis, scleroderma, systemic lupus erythematosus and cryoglobulinaemia.
