  1. Callus

    A callus 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.

Chambers 20th Century Dictionary

  1. Callus

    kal′us, n. a thickening of the skin: a term employed in old surgical works for the exuded material by which fractures of bones are consolidated together. [L.]
