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 ...
Cutis marmorata telangiectatica congenita (CMTC) is a rare congenital vascular disorder that usually manifests in affecting the blood vessels of the skin. The condition was first recognized and described in 1922 by Cato van Lohuizen, [2] a Dutch pediatrician whose name was later adopted in the other common name used to describe the condition – Van Lohuizen syndrome.
Cutis marmorata (from Latin marmor, "marble") is a benign skin condition which, if persistent, occurs in Cornelia de Lange syndrome, trisomy 13 and trisomy 18 syndromes. [1] When a newborn infant is exposed to low environmental temperatures, an evanescent , lacy, reticulated red and/or blue cutaneous vascular pattern appears over most of the ...
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 ...

But, if you're comparing flu A vs. flu B, it's impossible to tell which strain you have based just on your symptoms. "They're clinically indistinguishable on a case-by-case basis," Ray says.
Perhaps the most famous group of spiders that construct funnel-shaped webs is the Australian funnel-web spiders. There are 36 of them and some are dangerous as they produce a fast-acting 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 ...
