Ecchymosis is a skin problem that is characterized by a red or blue discoloration of the skin. It does not appear to be raised like acne and is a result of one or more underlying medical conditions. Ecchymosis is not a bruise, though it appears to be like one. It is a subcutaneous spot which is a result of blood fleeing into the tissues from broken blood vessels. It is usually bigger than 1 cm in and in some cases as big as 4-5 cm.
