Morphea, also known as localized scleroderma, is a condition which causes hardening and discoloration of the skin. It is thought to be isolated to the skin without internal organ involvement as seen in systemic sclerosis (commonly known as scleroderma).
Signs and symptoms of morphea can vary depending on the type and severity in each affected person. Morphea usually causes reddish patches of skin that thicken into firm, oval-shaped areas. The center of each patch may develop a lighter center. These patches sweat less than unaffected areas and may lose hair over time.
