Verrucae are warts on the feet, caused by the human papillomavirus. Although they can occur at any age, they are more common in children and teenagers. Some patients my have one verruca, while some, particularly those with a suppressed immune system, may have several larger verrucae which cover a large area of the foot.

The appearance of verrucae can vary, with some being smooth papules and others having a cauliflower-like texture, although each has the presence of thrombosed capillaries, giving them the appearance of black dots.

Verrucae can be painful due to the pressure exerted when a patient stand or walks, and although they sometimes regress spontaneously within months or years, treatment is often sought sooner due to this discomfort. Different treatments are recommended for different patients, but all require commitment from the patient and regular visits from a podiatrist, foot health practitioner or chiropodist.
