Pitted Keratolysis

Medically reviewed by Last updated on Dec 2, 2022.


Pitted keratolysis (PK)

is a bacterial infection of the skin on the bottom of your feet or palms of your hands. It is usually caused by large amounts of moisture. You may be at risk for PK if your feet or hands sweat more than usual. You may also be at risk if you wear tight shoes or gloves for long periods of time, or you live in a humid place.

Common symptoms include the following:

You may have small cracks, pits, or holes in the bottom of your feet or palms. Your feet or palms may burn or itch. If PK affects your feet, your feet and shoes may smell bad.

Contact your healthcare provider if:

  • Your symptoms get worse or do not go away in 3 weeks.
  • You have questions or concerns about your condition or care.

Treatment for PK

includes antibiotics and ointments. Antibiotics may be given as a pill or a cream. You may need other treatments to help decrease foot or palm sweating. Do the following to manage and prevent PK:

  • Wash your feet and hands with antibacterial soap as directed. This will prevent the bacteria from spreading and decrease odor.
  • Change your socks 2 to 3 times each day. This will help keep your feet clean and dry.
  • Wear moisture-wicking synthetic socks. These socks will help keep your feet dry. Ask your healthcare provider where to buy these socks.
  • Let your shoes air-dry every day. This will help decrease moisture in your shoes. If possible, remove your shoes 2 times each day and let them dry.

Follow up with your doctor as directed:

Write down your questions so you remember to ask them during your visits.
