Picture of Morphea (Late Stage)
Morphea is the name for localized patches of scleroderma. Morphea produces reddish, thickened, oval-shaped patches of skin, usually on the chest, stomach, and back. Morphea can sometimes appear on the face, arms, and legs. Morphea usually improves on its own over a period of 3 to 5 years, but it may leave behind patches of dark or discolored skin. Rarely, muscle damage can result from morphea. The cause of morphea is unknown. Morphea is relatively rare. It is found about three times more often in women than men. Most patients are 20 to 50 years of age when they are diagnosed.
