Common Procedures


  • Excision of small lesions of the skin
    • head and neck
    • trunk and limbs

A skin lesion is an area of the skin that is different from the surrounding skin. This can be a lump, sore, or an area of skin that is not normal. Skin lesion removal is a procedure to remove the lesion. Which procedure you have depends on the location, size, and type of lesion.


  • Cryotherapy of lesions of skin

Cryotherapy is a procedure that uses extreme cold (liquid nitrogen) to destroy tissue. It’s often used to treat skin lesions, which are skin growths or patches that don’t look like the skin around them. Cryotherapy also helps save the area around the lesions and to reduce the scarring as much as possible.

Other Procedures

  • Biopsy of lesion of the skin
  • Biopsy of the skin (Rashes)
  • Drainage of lesion of the skin including abscesses
  • Steriod injections
  • Patch Testing (Inclusive of application, reading and reporting)

Patch Testing

Patch testing is a specialist procedure carried out by your dermatologist to find out whether your skin condition is caused or aggravated by an allergy to substances which have come into contact with your skin. This is called contact allergy.

Substances that cause an allergic reaction are called allergens. They can be found at home, at work or in leisure activities.

What will be tested?

There are a very large number of substances which are most frequently in contact with the skin such as latex, preservatives, metals, perfumes, cosmetics and plants among others. Additional allergens are sometimes added to this list if it is thought they may trigger your sensitivity.
