A skin wart is scientifically referred to as?

A skin wart is scientifically referred to as verruca, which is the correct terminology used in dermatology. Warts are benign growths on the skin that are caused by viral infections, specifically by the human papillomavirus (HPV). The term "verruca" encompasses various types of warts, including common warts, plantar warts (on the feet), and flat warts.

The other terms are related but refer to different skin anomalies. A papule is a small, raised, solid pimple or swelling on the skin, often less than 1 centimeter in diameter, and may or may not be associated with a wart. A cyst is a closed sac-like structure that can be filled with fluid, pus, or other material, and does not refer specifically to warts. Lastly, a lesion is a general term that describes any abnormality on the skin that can be a result of various conditions, including warts, but is not specific to them. Therefore, the precise scientific term for a skin wart is indeed verruca.
