SKIN COLOR
The color of the skin is often altered in disease. It is yellow in jaundice, and is bluish, especially over the face, in congenital heart disease. There is a purplish tint around the eyes and mouth, with a prominence of the veins of the face, in weakly children or in those with disordered digestion. A pale circle around the mouth accompanies nausea. The skin frequently acquires an earthy hue in chronic diarrhea, and is pale in any condition in which the blood is impoverished, as in Bright's disease, rickets, consumption, or any exhausted state. Flushing of the face accompanies fever, but besides this there is often seen a flushing without fever in older children the subjects of chronic disorders of digestion. Sudden flushing or paling is sometimes seen in disease of the brain.
