Answer

The process typically begins in the distal fingers and advances proximally.

The process also may occur on the face, over the forehead, and around the mouth. Facial involvement can lead to a mauskopf (mouse head) appearance. Lips become thinner, and radial furrowing develops around the mouth. The oral aperture is reduced in size (microstomia). Wrinkles over the forehead diminish.
