Warts tend to be rougher, with a âwartyâ irregular surface whereas skin tags are usually smooth. Warts tend to be flat whereas tags are more like bumps hanging from thin stalk. While warts are almost entirely caused by human papilloma virus (HPV), tags are only sometimes associated with HPV.
Images of Wart, Flat (HPV) Overview. A flat wart, or verruca plana, is a form of wart (verruca). Warts are common growths caused by an infection of the surface (superficial) skin with the human papillomavirus (HPV), which thickens the top skin layer. Warts are usually harmless and painless, and many go away on their own after months to years.
