Corns

What are Corns?
1. Corns are common skin lesions in which there is a localized area of thickened skin which is also similar to calluses.

2. A corn (clavus, heloma) is painful and inflamed.

3. If the surface skin is damp and peeling, the corns will be referred to as soft corns. For example, corns located between toes that are squashed together.

4. A callus (tyloma) is an area of painless, hard and thick skin, and is subjected to friction.

5. Palmar or plantar keratoderma is a thick skin that appears on the entire palm or sole. This term is also used for genetic disorders when there are multiple areas of punctate keratoderma(callus).

At Royal Lush Skin Clinic, Dr. Syed and his team offer customized treatments with best and effective results and ensure minimum downtime.

What causes corns and calluses?

1. Caused by the response to friction and pressure.

2.  Repetitive injury results in the skin trying to protect itself from blistering.

3. Thicker prickle cell layer and thicker stratum corneum on the skin surface results due to increase in the basal epidermal cells (keratinocytes) in number.

Common sites of corns are:

Hands and feet but any area of the skin may be affected. The areas which are most commonly affected by corns are -

  • On the palms, from holding a racquet or hammer

  • On the knuckles (pushing oneself out of a wheelchair)

  • On the side of the foot because of tight shoes

  • On the ball of the foot ( running barefoot )

Precautions that need to be considered:

  • To relieve the pressure on the affected area of skin

  • You should choose well-fitted comfortable and flat footwear

  • Repetitive tasks that injure the skin shall be carried out by wearing leather gloves to take care of the skin and avoid friction

  • To reduce friction, apply a protective corn plaster or cushion to apply pressure more evenly around the affected area.

  • Use soft cotton, lamb's wool, moleskin or web spacers to separate toes.

  • To reduce the thickness

  • Sandpaper, file or pumice the affected surface because it will be easier when the skin has been soaked in warm water for few minutes or for a longer period of time.

  • Using a specially designed corn trimmer to pare down the surface.

  • Apply keratolytic creams or heel balms.

  • To ease the discomfort of painful cracks (fissures):

  • Apply a thick and lubricating ointment such as petroleum jelly

  • Seal the surface with adhesives

  • Use antibiotic ointments in case of infection and to reduce the chances of infection

  • Cover the surface with a thick adhesive plaster
