Which condition is a viral infection on the top layer of the skin that can spread, including plantar warts?

• A. Verruca
• B. Acne
• C. Steatoma
• D. Lukoderma

Answer: (A)

Verruca refers to a wart caused by the human papillomavirus invading the epidermis. This viral infection affects the top layer of the skin, producing a rough, raised lesion that can spread to adjacent areas or to others through direct contact or shared surfaces. Plantar warts are simply warts that appear on the soles of the feet, caused by the same virus and often felt when standing due to pressure. Other options describe conditions with different causes—acne is an inflammatory condition of hair follicles, steatoma is a sebaceous cyst, and lukoderma is a pigment loss disorder—so they don’t fit the description of a contagious viral infection of the skin’s surface.
