What is Corns and calluses?

13:47 - 25 October , 2023


It is the appearance of rough, thick skin layers that form on the hands and feet as a form of skin defense mechanism against excessive friction due to repetitive movement or pressure.

The main causes of the appearance of corns and calluses are:

  • Stop wearing socks.
  • Work or use tools with your bare hands.
  • Play musical instruments.
  • Hereditary tendency to generate calluses.
  • Wearing inappropriate, tight, or loose footwear.
  • Socks with little elastic.

Corns and calluses usually disappear on their own when the source of pressure or friction is eliminated, although if they are very large and painful, they will need to be treated.

It is necessary to distinguish between corns and calluses:


  • Small.
  • Deep.
  • Hard.
  • They hurt when pressed.


  • Painless.
  • Large.
  • Varied shapes.

Signs and symptoms Corns and calluses

Diagnosis and treatment Corns and calluses

The doctor will analyze your symptoms and clinical history and will perform a physical examination of the area where the lesions are located, removing some layers of hardened skin to confirm that they are corns and calluses.

The treatment to follow consists of:

  • Stop performing the repetitive movements that caused the condition.
  • Wear appropriate footwear and put insoles.
  • Remove excess skin with a scalpel.
  • Salicylic acid patch.
  • Surgery.
