Corns and Calluses

Corns and Calluses

Corns and calluses, also known as hyperkeratosis, develop as the body’s way of protecting itself from external pressure. These are common on people of all ages. When the body has an area that’s under pressure, it reacts by thickening the skin on that area. This can result in either corns or calluses, both of which are types of hyperkeratosis.

Corns are typically small, occur over bony prominences, and have a hard core. They are most common on the top of small toes or on the outside of the little toe. Calluses cover a larger area and are usually on the sole of the foot under the toes. This area takes the most weight when you walk.

Both conditions are typically painless, although sometimes a patient may experience pain or a burning sensation. Corns and thick calluses can sometimes feel like you’re walking on a pebble. The most obvious sign of a callus or corn is hardened, thick, yellow skin. Often, the skin will be less sensitive to touch as well.
