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 ...
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 racemosa and livedo reticularis are the most common manifestations in skin, although other symptoms such as digital necrosis, subcutaneous nodules, and non-specific rash have been seen. The most common neurological manifestations of DADA2 are secondary to vasculitis.
