They are a flat or common wart with a smooth pearly epidermal elevation. A contagious viral infection that forms firm papules with a rough surface varying in size. Warts are usually found on the hands but can spread to other areas of the face and body.
Warts can develop individually or in clusters, and can spontaneously disappear. There are various types of warts, including flat (plane), raised (common) and verrucas (plantar).
They are epidermal tumours of viral origin (human papilloma virus) and all can be treated. All warts are viral except Seborrhoeic Warts which are a thickening of the skin due to ageing.
The black dot sometimes visible in a wart are the capillaries supplying blood. Flat warts occur mostly on the face, backs of hands and wrists. They may itch. Strict hygiene procedures must be followed to avoid cross infection.
