Overview
A callus is a skin condition that occurs when the skin is subjected to pressure and forms a hard, thick surface to protect itself. Calluses are most commonly found on the soles of the feet and the toes but can be found anywhere that the skin is consistently under pressure, including the fingertips (particularly in musicians) and palms. A callus is similar to a corn, which is also a thick growth of skin on the feet or toes, but a corn tends to cover a smaller surface area and has a central core of softer skin, where a callus tends to be larger and without a central core. Calluses are not contagious, but other contagious conditions such as athlete's foot can mimic callus, and it is important to discuss any concerns with your doctor. There is no cure for calluses, but the regular use of certain creams and sometimes files or pumice stones can keep them under control.
