What is the term used for a wart?

The term "verruca" specifically refers to a wart, which is a benign growth on the skin caused by the human papillomavirus (HPV). Warts can appear in various forms and locations on the body, and verrucae are characterized by their rough texture and raised appearance. Identifying warts correctly is essential in a nail technician's practice, as these growths can affect nail services and overall skin health.

Understanding the distinctions between other terms can clarify why "verruca" is the correct answer. A papule typically refers to a small, raised bump on the skin, which may not necessarily be a wart and can represent other conditions. A pustule describes a small, inflamed blister that is filled with pus, often indicating infection or irritation, while a lesion is a broader term that encompasses any abnormal tissue change, which could include warts but is not specific to them. Thus, "verruca" is the precise term indicating the specific type of skin growth associated with warts.
