Common warts most commonly occur on the hands and around the nails. They may occur as single or multiple lesions, and appear as flesh-coloured nodules with a rough surface and small pit-point blood vessels. They may bleed if the surface is scratched or pared.
Flat warts occur commonly on the face, neck, arms, and legs. They are usually seen as smooth, flesh-coloured, pink or brown, flat-topped papules.
Plantar warts occur on the soles of the feet and toes and may be painful on pressure (eg. walking). It may be difficult to differentiate from corns (calluses).
Ano-genital warts occur around the genitals and are uncommon in children. Although most often transmitted sexually in adults, this is rarely the case in children, when it can occur through non sexual contact.
