Flat warts are small, smooth, slightly raised skin growths caused by certain strains of the human papillomavirus (HPV). Unlike common warts, flat warts are usually tiny, have a flatter surface, and often appear in clusters. They are most commonly found on the face, forehead, neck, hands, and legs.Flat warts are more common in children, teenagers, and young adults, but they can occur at any age. The virus spreads through direct skin contact or through small cuts and irritation caused by shaving, scratching, or friction. Because they are contagious, flat warts may spread to nearby areas of the skin if touched frequently.These warts are typically skin-colored, pink, or light brown and are usually painless.
