Definition of Corns
Medically reviewed by Min Clinic Staff | Updated: January 2026
Corns: Small calloused areas of skin caused by local pressure irritating tissue over a bony prominence. Corns most commonly occur over a toe where they form what is referred to as a hard corn. Between the toes, pressure can form a soft corn of macerated skin which often yellows.
The word corn comes from the Latin cornu meaning horn or hoof. A corn on the toe is also called a clavus.
