A callus (or callosity) is a toughened area of skin which has become relatively thick and hard in response to repeated friction, pressure, or other irritation. Rubbing that is too frequent or forceful will cause blisters rather than allow calluses to form. Since repeated contact is required, calluses are most often found on feet because of frequent walking. Calluses are generally not harmful, but may sometimes lead to other problems, such as skin ulceration or infection.
A corn or callus is an area of thick, hardened, dead skin, caused by friction and irritation. Corns form on the sides and tops of the toes, and can be quite painful. A callus typically forms on the bottom or sides of the feet and can be uncomfortable and unsightly, but does not usually become painful. The core consists of thick and dense skin tissue. 2  The core of the corn points inward and often presses on a bone or nerve which causes it to be quite painful. 3  A callus does not have a core, and is a broader area that is made of evenly distributed thicker tissue.
