Livedo reticularis is a common skin finding consisting of a mottled reticulated vascular pattern that appears as a lace-like purplish discoloration of the skin. [1] The discoloration is caused by reduction in blood flow ( ischemia ) through the arterioles that supply the cutaneous capillaries , resulting in deoxygenated blood showing as blue ...
Livedo racemosa or, less commonly, livedo reticularis are symptoms of such thrombosis, which causes blood and pressure to build up in the dermal superficial veins. [8] The oxygen partial pressure in the skin decreases as a result of the blood flow obstruction, triggering a cutaneous response that presents as pruritus with itchy papules and ...

Livedo reticularis appears as a bluish-purple, netlike mottling of the skin. Sneddon's syndrome may instead present with livedo racemosa, which involves larger, less organized patches of bluish-purple mottling of the skin. Both are generally found first in the extremities, both worsen in cold and either may occur without Sneddon's syndrome or ...
Nodules, livedo reticularis, ulcers, and gangrene. [27] Primary central nervous system vasculitis Headache, cognitive impairment, stroke, encephalopathy, and seizures. [28] Retinal vasculitis: Visual impairments, floaters, and macular edema. [29] Secondary vasculitis [8] Lupus vasculitis
Most commonly this causes skin symptoms (usually livedo reticularis), gangrene of the extremities and sometimes kidney failure; problems with other organs may arise, depending on the site at which the cholesterol crystals enter the bloodstream. [2] When the kidneys are involved, the disease is referred to as atheroembolic renal disease. [3]
Other skin abnormalities include thickening, hypertrichosis, acquired facial lipoatrophy, and infiltrating livedo reticularis with necrosis. POEMS syndrome can also cause Vascular-type skin changes including acrocyanosis, flushing, hyperaemia, and Raynaud's phenomenon. Nail changes consist of leukonychia and clubbing. [11]
