Corn (Kapalan/Kulit Keras) vs Wart (Ketuat): Difference and Getting Treatment in KL

Foot bump? It might be a corn or a wart — and knowing the difference matters.

Have you noticed a hard bump, thickened spot or rough patch on your foot and wondered whether it’s just a corn or maybe a wart? Making the right call matters. The cause and treatment for each are different. At KL Foot Specialist Podiatry, we help people in Kuala Lumpur get the correct diagnosis and treatment fast so foot-pain doesn’t limit your activity or lifestyle.

What Is a Corn?

It is important to differentiate a corn from a wart as one spreads easily while the other doesn't.

Thickened area of skin

A kind of protective response by your body to friction or repeated pressure, often from shoes, certain foot shapes or structural changes.

You’ll commonly find corns:

  • On the top or side of toes

  • Between toes (soft corn)

  • Under the ball of the foot or toes if your gait or shoe is causing extra pressure.

  • Corns are not caused by a virus and they’re not contagious. Because they arise from pressure, they’re often easier to prevent and treat by removing the source of pressure.

A corn may start as a minor discomfort. A small hard patch of skin that rubs against your shoe. But over time, the constant friction and pressure cause the corn to grow deeper, pressing into sensitive tissues beneath the skin.

If left untreated, this can lead to:

  • Sharp, stabbing pain with every step; especially when walking barefoot or wearing tight shoes.

  • Inflamed or infected skin, as bacteria can enter through cracks or breaks.

  • Altered walking posture. Many people subconsciously change how they walk to avoid pain, leading to knee, hip, or lower back strain.

  • Difficulty performing daily tasks, such as walking to work, driving, exercising, or even standing for long periods.

  • Reduced quality of life, as persistent foot pain makes even simple activities like going for a walk with your family - uncomfortable.

A small corn might seem harmless, but when ignored, it can deeply affect your mobility, comfort, and overall foot health.

 

What Is a Wart (Specifically a Plantar Wart)?

A plantar wart (sometimes called a verruca) is a growth caused by the human papilloma virus (HPV) that enters your skin through small breaks.

These often appear:

  • On the sole of the foot or under the heel, or in weight-bearing regions

  • With a rough surface and often small black pin-dots (capillary spots) visible

  • They may bleed slightly when scraped and can spread or cluster if left untreated
    Warts are contagious in the right conditions (e.g., communal showers, moist floors) and the treatment focuses not just on surface removal but eliminating or containing the viral infection.

Unlike corns, warts (plantar warts) are contagious and can spread to other parts of the foot, or even to your hands and family members. They often appear as rough, grainy patches with small black dots (tiny blood vessels).

If untreated, warts can:

  • Spread to form clusters (mosaic warts)

  • Cause deep pain under pressure points

  • Become harder to treat over time as the virus spreads deeper into the skin

When to see a podiatrist at KL Foot Specialist

  • If you’re not sure whether the bump is a corn or a wart

  • If it’s painful, growing, spreading or causing walking problems
