Corns and Calluses

A callus is a hard, yellowish plaque of dead skin that forms in reaction to recurring friction or other irritation on specific points of the skin. A corn is a specialized callus that develops into a localized cone from pressure rubbing in an elliptical shape. While calluses are generally harmless, acting as protective layers of hardened skin, corns can cause immense discomfort — the centre point of the corn pushes into the skin, causing the patient pain.

Because calluses and corns require recurrent contact, they are predominately found on feet where shoes rub while walking. Corns can also be found between toes. If left untreated, corns can break down the underlying tissues, leading to infection or ulceration. If the source of irritation is avoided, calluses and corns may eventually go away. A chiropodist, however, can quickly and harmlessly remove calluses and corns through paring or keratolytic treatment.
