Types of warts and verrucas

Common warts are painless, benign growths that consist of a hard core of skin. A common wart looks like a firm raised lump with a rough surface, often segmented, they have a cauliflower-like appearance. Warts can be round or irregular in shape, flat or raised, and can grow as large as a pea. They can be various shades of white, grey or brown. Common warts typically grow around fingernails, on the fingers and on the backs of hands, but they can also be found on the knees and elbows, most often where the skin has been previously broken.
