Dupuytren's contracture typically progresses slowly, over years. The condition usually begins as a thickening of the skin on the palm of your hand. As it progresses, the skin on your palm might appear puckered or dimpled. A firm lump of tissue can form on your palm. This lump might be sensitive to the touch but usually isn't painful.
In later stages of Dupuytren's contracture, cords of tissue form under the skin on your palm and can extend up to your fingers. As these cords tighten, your fingers might be pulled toward your palm, sometimes severely.
The ring finger and pinky are most commonly affected, though the middle finger also can be involved. Only rarely are the thumb and index finger affected. Dupuytren's contracture can occur in both hands, though one hand is usually affected more severely.
