The place of occurrence differentiates between soft and hard corns. Hard corns are called heloma durum, while soft corns are called heloma molle. "Corn" used to be a generic term for grain, and the name stuck. The hard part at the center of the corn resembles a barley hare, that is, a funnel with a broad raised top and a pointed bottom. The name corn comes from its appearance under the microscope. If there is constant stimulation of the tissues producing the corns, even after the corn is removed or the pressure surgically removed, the skin may continue to grow as a corn. Corns form when the pressure point against the skin traces an elliptical or semi-elliptical path, the center of which is at the point of pressure, gradually widening. They can sometimes occur on the thicker palmar or plantar skin surfaces. Frequent use of a writing implement may lead to a callus on the middle finger, commonly known as a "writer's bump".Ĭorns (also called clavi) are specially-shaped calluses of dead skin that usually occur on thin or glabrous (hairless and smooth) skin surfaces, especially on the dorsa of toes or fingers. Video game players may develop calluses on their thumbs, especially if using a controller with a poor D-pad. Dancers often develop calluses on the soles of their feet from dancing barefoot, which makes performing turns less difficult. String instrument players develop calluses where their fingers make contact with the strings, but these calluses are often desirable as they help alleviate the pain from the tension of the strings and make playing easier. Shoes that fit tightly can often produce calluses on the feet. Calluses are generally not harmful, but may sometimes lead to other problems, such as infection. Since repeated contact is required, calluses are most often found on hands or feet. In botany, the term is also used to announce a condition of thickened surfaces of leaves or other plant parts. OverviewĪ callus (or callous) is an especially toughened area of skin which has become relatively thick and hard as a response to repeated contact or pressure.
