What are warts?
Wart, known in surgery by the Latin name Verrucae, is a collection of lengthened papillae of the skin, closely adherent and ensheathed by a thick covering of hard dry cuticle. From friction and exposure to the air the surface presents a horny texture, and is rounded off into a small button-like shape. Such is the description of the simple wart, which is so commonly seen on the hands and fingers (and rarely on the face or elsewhere) of persons of all ages, but especially of children. Among other varieties of warts are: 1) Sublingual warts, growing, as their specific name implies be-neath or at the side of the finger or toe nails. They originate beneath the nail, and as they increase they crop out either at the free extremity or the side of the nail, and are usually troublesome and often very painful. 2) Venereal warts, caused by the direct irritation of the discharges of gonorrhea or syphilis, and occurring about the parts which are liable to be polluted with such discharges. They attain a larger size, and are more fleshy and vascular than other warts.
