Verrucae is a medical term that refers to warts on the skin. They are caused by the human papillomavirus (HPV) and can be spread through contact. There are several synonyms for verrucae, including wart, papilloma, condyloma, and verrucous lesion. Warts can appear on any part of the body but are most commonly found on the hands and feet. They can be treated by cryotherapy, where the wart is frozen off, or with topical creams that contain salicylic acid. It is important to seek medical attention if you have verrucae that are causing discomfort or are in a particularly sensitive area, such as the genital or facial region.
