Verruca or Corn?

We often see patients who are unsure whether they have a verruca or a corn. While both can appear on the feet and cause discomfort, they are distinct conditions requiring different treatments. Knowing the difference can help you seek the right care and manage the problem effectively.

What Is a Verruca?

A verruca, also known as a plantar wart, is caused by the human papillomavirus (HPV). It typically appears on the soles of the feet and can spread through direct contact, such as walking barefoot in communal areas like swimming pools and gyms. Verrucae are often characterised by:

• A rough, cauliflower-like surface
• Small black dots (which are tiny blood vessels)
• Pain when pinched from the sides
• Potential clusters forming in a mosaic pattern

Since verrucae are viral infections, they can spread to other parts of the body or to other people. Over time, they may go away on their own, but many patients opt for treatment due to pain or persistent growth.

What Is a Corn?

A corn is a thickened area of skin caused by repeated pressure or friction, typically from ill-fitting shoes or abnormal foot mechanics. Unlike verrucae, corns are not caused by a virus and are not contagious. Corns often present with:

• A central core that presses into the skin, causing pain
• A hard, yellowish, and well-defined appearance
• Pain when direct pressure is applied (rather than when pinched)
• Development in areas of repeated friction, such as the tops of toes or the ball of the foot

Corns do not resolve on their own and require proper foot care and footwear adjustments to prevent recurrence.

How to Tell the Difference

To differentiate between a verruca and a corn is by squeezing the affected area. If squeezing from the sides causes pain, it’s likely a verruca. If direct pressure from above is painful, it’s more likely a corn. However, professional diagnosis from a podiatrist is always recommended to ensure the correct treatment.

Treatment Options

• For Verrucae: Treatments include swift microwave therapy and Faulkner’s needling, as verrucae are caused by a virus, the immune system also plays a role in their resolution.
• For Corns: Treatment focuses on removing the thickened skin and addressing the underlying cause, such as changing footwear, using protective pads, or orthotic support to reduce pressure.
