Erythema: Excerpt from Handbook of Signs & Symptoms (Third Edition)

Erythroderma

Dilated or congested blood vessels produce red skin, or erythema, the most common sign of skin inflammation or irritation. Erythema may be localized or generalized and may occur suddenly or gradually. Skin color can range from bright red in patients with acute conditions to pale violet or brown in those with chronic problems. Erythema must be differentiated from purpura, which causes redness from bleeding into the skin. When pressure is applied directly to the skin, erythema blanches momentarily, but purpura doesn't.

Erythema usually results from changes in the arteries, veins, and small vessels that lead to increased small-vessel perfusion. Drugs and neurogenic mechanisms can allow extra blood to enter the small vessels. Erythema can also result from trauma and tissue damage; changes in supporting tissues, which increase vessel visibility; and many rare disorders. (See Rare causes of erythema.)
