Which condition is thickened skin due to repeated friction and pressure?

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

Answer: (B)

Thickened skin caused by repeated rubbing or pressure is a protective callus. The skin responds by increasing keratin in the outer layers, forming a broad, diffuse patch usually on weight-bearing areas like the soles or palms. Calluses tend to be flat or slightly raised and are generally painless, unlike other thickened spots that come from different processes. Corns also involve thickened skin but are more localized with a central core and are often painful when pressed, typically over bony areas. Warts are caused by HPV and have a rough surface with tiny dark dots, not just friction-related thickening. Eczema is an inflammatory skin condition with itching, redness, and flaking, not a friction-induced thickening.
