Common warts

**Definition:** Common warts are due to an infection of the epidermis by certain human papilloma viruses, most commonly HPV subtypes 1, 2, 4, 27 and 57. They manifest typically as papillomatous, keratinous growths on the hands and feet but may affect any part of the skin (and also adjacent mucous epithelia). They are very common during childhood and adolescence.

**Exclusions:** - Warts of lips or oral cavity
