Epidermodysplasia verruciformis (EV) is a skin condition characterised by warty skin lesions. [1] It results from an abnormal susceptibility to HPV infection (HPV) and is associated with a high lifetime risk of squamous cell carcinomas in skin. [1]

Plantar wart ( verruca , verruca plantaris ), a hard, sometimes painful lump, often with multiple black specks in the center; usually only found on ...
Common warts have a characteristic cauliflower-like surface and are typically slightly raised above the surrounding skin. Cutaneous HPV types can cause genital warts but are not associated with the development of cancer. [citation needed] Plantar warts are found on the soles of the feet; they grow inward, generally causing pain when walking.
Plantar warts are often similar to calluses or corns, but can be differentiated by close observation of skin striations. Feet are covered in friction ridges, which are akin to fingerprints of the feet. Friction ridges are disrupted by plantar warts; if the lesion is not a plantar wart, the striations continue across the top layer of the skin.
[a] Its main current use in pharmacology is treating molluscum contagiosum and warts topically. [2] It is a burn agent and poisonous in large doses, and has been historically used as aphrodisiacs (Spanish fly).
