Warts
Key Points
Cutaneous warts are caused by human papillomaviruses, are very common, and have multiple forms. Spread is usually by autoinoculation and is facilitated by trauma and maceration. Most warts are asymptomatic but can be mildly painful with pressure. Most warts resolve spontaneously, particularly common warts. Treatments, when indicated, commonly include topical irritants (eg,salicylic acid,cantharidin,podophyllumresin) and/or destructive methods (eg, cryosurgery, electrocautery, curettage, excision, laser). Recalcitrant warts can be treated with other intralesional and oral agents as well as the 9-valent HPV vaccine.
