Which term is a lesion caused by a virus on the bottom of the feet that can spread?

• A. Morton's neuroma
• B. Verruca plantaris
• C. Ingrown nail
• D. Nail avulsion

Answer: (B)

Verruca plantaris refers to a plantar wart, a lesion on the bottom of the foot caused by human papillomavirus. It’s a viral, contagious growth that can spread to surrounding skin or to others through direct contact or shared surfaces, especially in weight-bearing areas of the sole. This distinguishes it from the other options: Morton's neuroma is a nerve-related lump between toes, not viral; an ingrown nail is nail edge growing into the surrounding skin; and nail avulsion is a procedure to remove the nail.
