Warts are unsightly, often painful skin growths caused by the human papillomavirus (HPV). There are several synonyms for the word "warts," including verrucae, papillomas, growths, or lesions. Plantar warts refer specifically to those that appear on the soles of the feet, while genital warts are located on or around the genitals. Warts can vary in size and shape, and may be smooth or rough in texture. They can be treated with topical medications, freezing, or even surgical removal. It's important to seek medical attention for warts, particularly if they are widespread or persist despite treatment.
