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 through the arterioles that supply the cutaneous capillaries, resulting in deoxygenated blood showing as blue discoloration ().
Stasis dermatitis is diagnosed clinically by assessing the appearance of red plaques on the lower legs and the inner side of the ankle. Stasis dermatitis can resemble a number of other conditions, such as cellulitis and contact dermatitis, and at times needs the use of a duplex ultrasound to confirm the diagnosis or if clinical diagnosis alone is not sufficient.
Schamberg's disease is caused by leaky blood vessels near the surface of the skin, capillaries, which allow red blood cells to slip through into the skin. [3] The red blood cells in the skin then fall apart and release their iron, which is released from hemoglobin. [3] The iron causes a rust color and this accounts for the orange tint of the ...
There are many causes of red, itchy, swollen patches of skin, including allergies, burns, and infections. Here are photos to help you identify what you have.
Swelling: Some individuals may experience slight swelling (edema) in the lower legs alongside the rash. This swelling is typically mild and localized to the affected areas. [3] [2] Burning sensation: A burning or stinging sensation in the affected skin is commonly reported. This discomfort can range from mild to moderate in intensity. [3] [6]
Erythema ab igne (Latin for 'redness from fire') EAI, also known as hot water bottle rash, [2] is a skin condition caused by long-term exposure to heat (infrared radiation). [3] Prolonged thermal radiation exposure to the skin can lead to the development of reticulated erythema , hyperpigmentation , scaling, and telangiectasias in the affected ...
There is severe burning pain (in the small fiber sensory nerves) and skin redness. The attacks are periodic and are commonly triggered by heat, pressure, mild activity, exertion, insomnia or stress. Erythromelalgia may occur either as a primary or secondary disorder (i.e. a disorder in and of itself or a symptom of another condition).
The red-purple color of the lesions is due to the inflammation in the blood vessels causing red blood cells to escape into the dermis skin layer. [ 6 ] Small fluid-filled blisters (or "vesicles"), pus-filled bumps resembling a pimple (or "pustules"), or shallow ulcers may also develop but are less common.
