Erythema means redness of the skin. It is caused by vasodilation of the capillaries and an increase of blood flow to the skin. Erythema disappears when pressure is applied to the skin, while a bruise or underlying bleeding in the skin and pigmentation do not. There is no increase in temperature with erythema, unless it is associated with the dilation of arteries in the deeper layer of the skin.
