Common warts

These are dome-shaped papules or nodules with papilliferous surfaces. They are rough, scaly, pink or skin-coloured and usually multiple. They are most common on hands or feet in children but may also be found on faces or genitalia. Their surfaces interrupt skin lines. Some facial warts can resemble a thread or filament (filiform appearance).

Plane warts
These are smooth, flat-topped papules which are often light brown in colour. They are most common on the face and dorsum of hands and usually multiple and painless. They are hard to treat and eventually resolve spontaneously. They can Koebnerise, i.e. appear in areas where the skin is injured.

Plantar warts
These are common in children and adolescents and can be solitary or multiple. They usually have a rough surface and affect the soles of feet, are painful and covered by callus. They grow into the dermis due to pressure.
