A filiform wart is distinct from other types of warts because of its long and narrow projections. It extends at about two millimeters from the skin. Its color ranges from yellow, pink, and brown to skin toned.
Before using any particular treatment, it is critical to confirm the bumps are actually flat warts. Flat warts are bumps that lie almost flush against the surface of the skin. These small bumps almost always appear in clusters. Flat warts have smooth tops and are flesh colored, or they may be yellow. These warts can spread easily to other parts of the face.
Periungual Wart Causes Like other types of warts, the Periungual wart is caused by the HPV or the human papilloma virus. This virus can be present among many people without showing any indication of a wart.
Plantar warts. Plantar warts are caused by the same type of virus that causes warts on your hands and fingers. But, because of their location, they can be painful.
