DefinitionBy Mayo Clinic Staff
Common warts are small, grainy skin growths that occur most often on your fingers or hands. Rough to the touch, common warts also often feature a pattern of tiny black dots — sometimes called seeds — which are small, clotted blood vessels.
Common warts are caused by a virus and are transmitted by touch. Children and young adults are more likely to develop common warts, as are people who have weakened immune systems. Common warts usually disappear on their own, but many people choose to remove them because they find them bothersome or embarrassing.
