cross section of a corn

The corn - A small area of thickened skin on a toe or other part of the foot. A corn is caused by the pressure of a tight-fitting shoe. The dead skin cells form a hard plug that extends down into the skin tissues.

Pressure on this plug can cause pain. If a corn is painful, a spongy ring or corn pad can be placed over it to relieve the pressure. If the corn persists, the area of thickened skin can be removed by a chiropodist.
