Corn description

Corn description

• A. A lesion caused by bacterial infection
• B. Similar to callus, involves discreet pressure typically over a bone
• C. Similar to callus but thicker
• D. A type of blister caused by heat

Answer: (B)

Corns are localized thickening of the skin caused by repeated pressure or friction, usually over a bony prominence on the foot. They resemble calluses in origin but are more focal and often painful when pressed, due to a small, central area of keratin buildup. The other descriptions describe infections, diffuse thickening, or heat-related blisters, which don’t fit a corn as well. So the description that best matches a corn is a focal lesion similar to a callus caused by discreet pressure over a bone.
