What are cutaneous warts?

Common warts are grainy skin growths that are rough to touch and most often occur on your fingers or hands. Sometime they feature a pattern of tiny black dots, which are small clotted blood vessels.

Flat warts are smooth, flat-topped, flesh- or brownish-yellow-coloured bumps the size of a pinhead. They’re commonly found on the face, back of the hands, or legs, and tend to appear in large numbers. Flat warts are also called juvenile warts because they’re most commonly found in children and young adults.

Plantar warts are growths that usually appear on your heels or other weight-bearing areas of your feet. This pressure may also cause plantar warts to grow inward beneath a hard, thick layer of skin.

Common, flat and plantar warts are caused by a virus and can be transmitted by touch, but are non-cancerous.
