An area of tough, thickened skin caused by pressure or friction. Calluses commonly develop on the palms, fingertips, and soles of the feet. Calluses are most often associated with specific types of work and sport. Calluses can cause tenderness or pain under the skin. Self-treatment of calluses includes using a file, pumice stone, or towel to rub away excess skin when the skin is damp. Medical treatment includes paring the thickened skin with a scalpel. In some cases surgery may be needed.
A localized region of skin thickening, commonly found on the hands or feet, resulting from repetitive or prolonged pressure or rubbing. A corn represents a specific type of callus that forms on a toe. In cases where corns cause discomfort, a podiatrist can delicately remove the thickened skin using a scalpel.
