These dark blue-grey lesions are most commonly seen in darker-skinned infants. The sacrum is the most commonly affected area. These lesions tend to fade over several years but may not completely disappear. No evaluation is needed. They can be easily differentiated from bruises by the absence of other colors associated with bruises -- red, purple, green, brown or yellow.
