Verruca – Patient Information

What is a Verruca? 

Verrucae, also known as Verruca Pedis, are benign (non-cancerous) skin lesions caused by the human papilloma virus (HPV). They are a type of wart and are most commonly found on the soles of the feet, especially in weight-bearing areas like the heel or the ball of the foot.

Common Causes 

• By HPV infection of the epidermis (top layer of the skin) 
• Spread via direct skin contact or contaminated surfaces (e.g. communal showers, swimming pools) 
• Virus enters through small breaks or cuts in the skin 

---

Symptoms 

• Often appear as rough, grainy, or cauliflower-like lesions 
• May be covered by a layer of hard skin (callus), especially in high-pressure areas
• Painful when pressed or walked on, particularly if they form inward due to pressure 
• Often show tiny black dots (capillary blood vessels) on close inspection

Treatment 

• Over-the-counter topical treatments (e.g. salicylic acid) 
• Verrutop – nitri-zinc vials applied every 2 weeks for up to 6 treatments
• Cryotherapy (freezing with Liquid Nitrous Oxide)
• Silver nitrate, cantharidin, or other chemical agents 
• Debridement of Verruca to relieve pressure and pain 
• Laser therapy or minor surgical removal (for persistent cases)
• Duct tape method or other occlusion therapies (mixed evidence) 
• No treatment, as verrucae can sometimes resolve spontaneously

Prevention 

• Wear flip-flops or shower shoes in communal areas
• Avoid touching or picking at verrucae 
• Keep feet clean and dry
• Avoid sharing shoes or towels 
• Cover verrucae with a plaster or dressing when swimming or exercising
