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).
Morphea looks like discoloured patches on the skin. Morphea makes patches called plaques or lesions appear on the skin. It usually begins with a whitish patch with a purple border. It often has the appearance of a bruise.
