Verruca

A wart (also known as verruca) is generally a small, rough tumor, typically on hands and feet but often other locations, that can resemble a cauliflower or a solid blister. Verrucas are slightly raised and circular in shape, with a thickened rim of surrounding skin.

There may be several verrucas or just one. Warts are common, and are caused by a viral infection, specifically by the human papillomavirus (HPV) and are contagious when in contact with the skin of an infected person.

It is also possible to get warts from using towels or other objects used by an infected person. HPV is associated with oral cancer, laryngeal cancers, tracheal and lung cancers.

In children, verrucas tend to come and go quite quickly, but in adults they can persist for several years if they are not treated.
