Callus is described as?

• A. Red, itchy patches in allergic reactions
• B. Wart
• C. Thread-like red lines on the skin
• D. Sometimes called hyperkeratosis or keratoma; a thickening of the epidermis

Answer: (D)

Callus is a thickening of the epidermis, often described as hyperkeratosis or keratoma. It develops when the skin is repeatedly subjected to friction or pressure, and the outer layer forms extra cells as a protective response. The result is a firm, sometimes yellowish patch on areas like the hands or feet. This is not red, itchy patches from allergic reactions, nor a wart caused by HPV, nor thread‑like red lines on the skin.
