Corns and Calluses (Hyperkeratoses) in Vancouver
Corns and Calluses are caused by the thickening of the outer layer of skin. It may occur as an inherited disorder, affecting the soles of the feet. A callus (or callosity) is an especially 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.
Glabrous (hairless and smooth) skin surfaces can form, especially on the
dorsal surface of toes or fingers, or on the thicker palmar or plantar skin surfaces.
A corn is a small patch of thickened, dead skin with a central core. A soft corn has a much thinner surface and usually occurs between the 4th and 5th toes. A seed corn is a tiny, discrete callous that can be very tender if it's on a weigh-bearing part of the foot. Seed corns tend to occur on the bottom of the feet, and some doctors believe this condition is caused by plugged sweat ducts.
