Pressure corns form when chronic pressure on the skin against an underlying bone traces a usually elliptical path during the rubbing motion. The corn forms at the center of the pressure point and gradually widens and deepens. Corns from an acute injury, such as a from a thorn in the sole of the foot, may form due to the weight of the body, when the process that creates the usually evenly developing plantar callus is concentrated at the point of the healing injury, as an internal callus may be triggered by pressure on the transitional scar tissue. A hard corn is called a heloma durum or clavus durus, while a soft corn is called a heloma molle or clavus mollis. Many languages have metaphoric phrases for corns. Several are based on the word for ‘eye’: e.
The hard part at the center of the corn resembles a barleycorn or shoe tack, that is, a cone or funnel shape with a broad top and a pointed tip at bottom. Because of their shape, corns intensify the pressure at the tip and can cause deep tissue damage and ulceration. The location of soft corns tends to differ from that of hard corns. Hard corns occur on dry, flat surfaces of skin. The corn’s center is not soft, however, but indurated. To exclude other differential diagnoses, a skin biopsy may be taken. Imaging studies can be used in order to detect any underlying bony abnormalities that cause abnormal pressure on the overlying skin.
Treatment of pressure corns includes paring of the lesions, which immediately reduces pain. Another popular method is to use a corn plaster, a felt ring with a core of salicylic acid that relieves pressure and erodes the hard skin. Corns formed around an acute injury occur in deeper tissue than pressure corns, they can usually be excised without cutting into the dermis, leaving only a thin layer of epidermis behind. The resulting hole in the sole of the foot may however form its own internal callus which triggers a new corn before it can fully heal, so it may be necessary to excise the corn more than once before the spot returns to an even plantar callus.

Brain tumor, breast cancer, colon cancer, congenital heart disease, heart arrhythmia. They often form on feet and toes or hands and fingers. If you’re healthy, you don’t need treatment for corns and calluses unless they cause pain or you don’t like how they look. For most people, simply removing the source of the friction or pressure makes corns and calluses disappear. They can vary in size and shape and are rarely painful.
Corns and calluses are not the same thing. Corns are smaller and deeper than calluses and have a hard center surrounded by swollen skin. They can be painful when pressed. Hard corns often form on the top of the toes or the outer edge of the small toe. Soft corns tend to form between the toes.
Calluses are rarely painful and tend to develop on pressure spots, such as the heels, the balls of the feet, the palms and the knees. They may vary in size and shape and are often larger than corns.
