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 ().
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 ...
Erythema nodosum (EN) is an inflammatory condition characterized by inflammation of subcutaneous fat tissue, resulting in painful red/blue lumps or nodules that are usually seen symmetrically on both shins, on the thighs, arms, and elsewhere. [1] It can be caused by a variety of conditions but 20 to 50% of cases are idiopathic.
Erythema marginatum (also known as chicken wire erythema) [1] is an acquired skin condition which primarily affects the arms, trunk, and legs. [2] It is a type of erythema (redness of the skin or mucous membranes) characterised by bright pink or red circular lesions which have sharply-defined borders and faint central clearing.
Typically it results in a red, itchy, scaly, circular rash. [1] Hair loss may occur in the area affected. [1] Symptoms begin four to fourteen days after exposure. [1] The types of dermatophytosis are typically named for area of the body that they affect. [2] Multiple areas can be affected at a given time. [4]
A maculopapular rash is a type of rash characterized by a flat, red area on the skin that is covered with small confluent bumps. It may only appear red in lighter-skinned people. The term "maculopapular" is a compound: macules are small, flat discolored spots on the surface of the skin; and papules are small, raised bumps.
A spider angioma or spider naevus (plural: spider naevi), also nevus araneus, is a type of telangiectasis [2] (swollen, spider-like blood vessels on the skin) found slightly beneath the skin's surface, often containing a central red spot and deep reddish extensions (see Blood color) which radiate outwards like a spider's web or a spider's legs.
The management of lipodermatosclerosis may include treating venous insufficiency with leg elevation and elastic compression stockings. [9] In some difficult cases, the condition may be improved with the additional use of the fibrinolytic agent, stanozol. Fibrinolytic agents use an enzymatic action to help dissolve blood clots.
