What is a Verruca?
What Is a Verruca (Plantar Wart)? causes, symptoms, and treatment
A verruca, also known as a plantar wart, is a small, rough skin lesion caused by the human papillomavirus (HPV). Verrucae usually appear on the bottom of the foot or toes and can easily be mistaken for a corn or callus. While they are typically less than 1 cm in diameter, verrucae can grow larger or appear in clusters, known as mosaic warts.
What causes a verruca?
The HPV virus responsible for verrucae is common in the environment and thrives in warm, damp areas — such as communal showers, gyms, saunas, and around swimming pools. The virus enters the body through small cuts, cracks, or abrasions in the skin, which is why they often develop on weight-bearing areas of the foot.
Children and teenagers are particularly susceptible because their immune systems are still developing, but adults can also become infected, especially if their immune system is compromised or they frequently walk barefoot in public areas. Verrucae can spread easily from person to person, or even from one part of the body to another, through direct contact.
Recognising a verruca
Verrucae can vary in appearance, but common signs include:
-
A small, round or oval lesion with a rough, grainy surface
-
A hard skin layer over the top, resembling a corn
-
Tiny black dots (clotted blood vessels) visible in the centre
-
Pain or tenderness when standing or walking
-
Discomfort when pressure is applied to the area
Because verrucae look similar to corns or calluses, a professional diagnosis is important to ensure correct treatment.
Treatment options for verrucae
At Waikato Podiatry, we offer several evidence-based treatments for verrucae pedis, tailored to the size, depth, and duration of the lesion. The right treatment will depend on your specific condition, overall health, and lifestyle needs.
Conservative treatments may include:
-
Debridement and topical therapy: removing the overlying hard skin and applying medicated solutions to target the virus.
-
Occlusive treatments: covering the verruca to encourage the immune system to respond naturally.
-
Cryotherapy: freezing the verruca using liquid nitrogen to destroy the affected tissue.
For persistent or painful verrucae, we may recommend a minor surgical procedure. This involves using a local anaesthetic to numb the area and remove the verruca in one visit. Healing usually takes around 2–4 weeks, depending on the lesion’s size and location.
