The term âcornâ is often used interchangeably with callus. Essentially, they are both caused by the same thing, but visually a corn is often smaller, rounder and deeper, and a callus is usually broader, covering a larger area. A âbunionâ is the name for the enlarged bony bump located behind the big toe at the joint where it attaches to the foot.
A corn (or clavus, plural clavi) is a specially-shaped callus of dead skin that usually occurs on thin or glabrous (hairless and smooth) skin surfaces, especially on the dorsal surface of toes or fingers. They can sometimes occur on the thicker palmar or plantar skin surfaces.oo much friction occurring too fast for the skin to develop a protective callus will cause a blister or abrasion instead. Biologically, calluses are formed by the accumulation of terminally undifferentiated keratinocytes in the outermost layer of skin.
