Which condition presents as a thickening or bump commonly formed on the tops or sides of the toes due to pressure?

• A. Burns
• B. Calluses
• C. Corns
• D. Warts

Answer: (C)

This is a corn. Corns form from repeated pressure or friction, usually from shoes rubbing on the tops or sides of the toes, creating a small, well-defined patch of hard skin that can have a central core and may be painful when pressed. This contrasts with calluses, which are broader, diffuse thickening on weight-bearing areas like the soles and aren’t a focused bump on the toes. Warts come from HPV and look rough with tiny dark dots, not simply a pressure-related thickening. Burns are injuries with redness and blistering, not a localized toe bump from pressure.
