Which condition is caused by pressure or friction and usually appears on the tops or sides of the toes?

• A. Calluses
• B. Eczema
• C. Corns
• D. Shingles

Answer: (C)

A corn forms when repeated pressure or friction from footwear causes the skin to thicken into a small, localized area. They usually show up on the tops or sides of the toes where a shoe rubs, and they often have a hard, central core that can be painful when pressed. This helps distinguish them from a callus, which is a broader patch of thickened skin on weight-bearing areas like the soles and is typically less painful. Eczema involves itchy, inflamed patches of skin, not a focal lesion from friction, and shingles presents as a painful, vesicular rash along a nerve distribution rather than a friction-related thickening.
