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.

Sneddon's syndrome may instead present with livedo racemosa, which involves larger, less organized patches of bluish-purple mottling of the skin.

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 refers to slowing of blood flow, leading to desaturation of blood and bluish discolouration of the skin. This type of skin rashes may be seen in cold-induced vasoconstriction as seen in polycythemia or other causes leading up to focal impairment of blood flow. [4]
As with most blood tests, false-negatives can happen, meaning results could come back negative when a cancer does exist — although Grail reports that negative cancer test results from Galleri ...
The cold is likely to stick around through the second weekend of January. This could leave the atmosphere primed to deliver snow and ice – potentially in places that don’t typically receive it.
Cold and mottled skin (livedo reticularis), especially extremities, due to insufficient perfusion of the skin The severity of hemorrhagic shock can be graded on a 1–4 scale on the physical signs. The shock index (heart rate divided by systolic blood pressure) is a stronger predictor of the impact of blood loss than heart rate and blood ...
In adults and children age 2 and older, use it only on the neck and chest to ease coughing during a cold, per the Mayo Clinic. Vicks VapoRub is made of ingredients such as camphor, eucalyptus oil ...
