Livedoid vasculitis

Livedoid vasculopathy (also known as "Livedoid vasculitis", "Livedo reticularis with summer/winter ulceration" and "Segmental hyalinizing vasculitis") is a chronic cutaneous disease seen predominantly in young to middle-aged women. One synonym used to describe its features is "Painful purpuric ulcers with reticular pattern of the lower extremities" (PURPLE).

It can be divided into a primary (or idiopathic) form and a secondary form, which has been associated with a number of diseases, including chronic venous hypertension and varicosities.
