Wart (Verruca vulgaris)

A wart is a small, rough growth resembling a cauliflower or a solid blister. It typically occurs on human’s hands or feet, but often in other locations. Warts are caused by a viral infection, specifically by one of the many types of human papillomavirus (HPV). There are as many as 10 varieties of warts, the most common considered to be mostly harmless. It is possible to get warts from others; they are contagious and usually enter the body in an area of broken skin. They typically disappear after a few months but can last for years and can recur.

Types of wart have been identified, varying in shape and site affected, as well as the type of human papillomavirus involved. These include:

Common wart (Verruca vulgaris)

A raised wart with roughened surface, most common on hands, but can grow anywhere on the body.

Flat wart (Verruca plana)

A small, smooth flattened wart, flesh-coloured, which can occur in large numbers; most common on the face, neck, hands, wrists and knees.

Filiform or digitate wart

A thread- or finger-like wart, most common on the face, especially near the eyelids and lips.

Genital wart (venereal wart, Condyloma acuminatum, Verruca acuminata)

A wart that occurs on the genitalia.

Mosaic wart
