Warts can appear anywhere on the body. When they develop on the hands, they often present as fleshy growths and are classified as common warts. They result from infection with the human papillomavirus (HPV) and represent benign skin proliferations. Typically, they manifest as firm, rough-surfaced, papule-like skin growths. Viral infection and a weakened immune system are the primary factors leading to wart development. Warts are considered to be related to the body's immune response and therefore can spread easily.
